Q. The digits 1,2,3,4,5 1,2,3,4,5 , and 66 are randomly arranged to form a three-digit number. (Digits are not repeated) Find the probability that the number is even and greater than 600600 .\newlineThe probability that the three-digit number is even and greater than 600600 is \square .\newline(Type an integer or a simplified fraction.)
  1. Determine Total Possible Numbers: To find the probability that the number is even and greater than 600600, we first need to determine the total number of possible three-digit numbers that can be formed with the given digits without repetition.
  2. Calculate Favorable Outcomes: There are 66 choices for the first digit, 55 choices for the second digit, and 44 choices for the third digit, since the digits cannot be repeated. This gives us a total of 6×5×4=1206 \times 5 \times 4 = 120 possible three-digit numbers.
  3. Find Probability: Now we need to find the number of favorable outcomes, which are the even numbers greater than 600600. Since the number must be even, the last digit must be 22, 44, or 66.
  4. Find Probability: Now we need to find the number of favorable outcomes, which are the even numbers greater than 600600. Since the number must be even, the last digit must be 22, 44, or 66.For a number to be greater than 600600, the first digit must be either 66. There is only 11 choice for the first digit.
  5. Find Probability: Now we need to find the number of favorable outcomes, which are the even numbers greater than 600600. Since the number must be even, the last digit must be 22, 44, or 66.For a number to be greater than 600600, the first digit must be either 66. There is only 11 choice for the first digit.Since the first digit is 66 and the last digit must be even, we have 33 choices for the last digit (22, 44, or 66). However, since 66 is already used as the first digit, we only have 22 choices left for the last digit (22 or 44).
  6. Find Probability: Now we need to find the number of favorable outcomes, which are the even numbers greater than 600600. Since the number must be even, the last digit must be 22, 44, or 66.For a number to be greater than 600600, the first digit must be either 66. There is only 11 choice for the first digit.Since the first digit is 66 and the last digit must be even, we have 33 choices for the last digit (22, 44, or 66). However, since 66 is already used as the first digit, we only have 22 choices left for the last digit (22 or 44).For the middle digit, we have 44 remaining digits to choose from (11, 33, 2299, or the unused even number). This gives us 44 choices for the middle digit.
  7. Find Probability: Now we need to find the number of favorable outcomes, which are the even numbers greater than 600600. Since the number must be even, the last digit must be 22, 44, or 66.For a number to be greater than 600600, the first digit must be either 66. There is only 11 choice for the first digit.Since the first digit is 66 and the last digit must be even, we have 33 choices for the last digit (22, 44, or 66). However, since 66 is already used as the first digit, we only have 22 choices left for the last digit (22 or 44).For the middle digit, we have 44 remaining digits to choose from (11, 33, 2299, or the unused even number). This gives us 44 choices for the middle digit.Multiplying the number of choices for each position, we get 11 (for the first digit) * 44 (for the middle digit) * 22 (for the last digit) = 4444 favorable outcomes.
  8. Find Probability: Now we need to find the number of favorable outcomes, which are the even numbers greater than 600600. Since the number must be even, the last digit must be 22, 44, or 66.For a number to be greater than 600600, the first digit must be either 66. There is only 11 choice for the first digit.Since the first digit is 66 and the last digit must be even, we have 33 choices for the last digit (22, 44, or 66). However, since 66 is already used as the first digit, we only have 22 choices left for the last digit (22 or 44).For the middle digit, we have 44 remaining digits to choose from (11, 33, 2299, or the unused even number). This gives us 44 choices for the middle digit.Multiplying the number of choices for each position, we get 11 (for the first digit) * 44 (for the middle digit) * 22 (for the last digit) = 4444 favorable outcomes.The probability is the number of favorable outcomes divided by the total number of possible outcomes. Therefore, the probability is 4455.
  9. Find Probability: Now we need to find the number of favorable outcomes, which are the even numbers greater than 600600. Since the number must be even, the last digit must be 22, 44, or 66.For a number to be greater than 600600, the first digit must be either 66. There is only 11 choice for the first digit.Since the first digit is 66 and the last digit must be even, we have 33 choices for the last digit (22, 44, or 66).

This gives us 44 choices for the middle digit.Multiplying the number of choices for each position, we get 11 (for the first digit) 4422 44 (for the middle digit) 4422 22 (for the last digit) 4466 4477 favorable outcomes.The probability is the number of favorable outcomes divided by the total number of possible outcomes. Therefore, the probability is 4488.We can simplify the fraction 4488 by dividing both the numerator and the denominator by 4477. This gives us 6611.
