Q. Dua dadu dilempar sekaligus sebanyak satu kali. Peluang muncul jumlah kedua mata dadu sama dengan 3 atau 10 adalah....
Calculate Total Outcomes: To solve this problem, we need to consider all the possible outcomes when two dice are rolled. Each die has 6 faces, so there are a total of 6×6=36 possible outcomes.
Determine Sum of 3 Outcomes: Next, we need to determine the number of outcomes that result in a sum of 3. The pairs that give a sum of 3 are (1,2) and (2,1). There are 2 outcomes that give a sum of 3.
Determine Sum of 10 Outcomes: Now, we need to determine the number of outcomes that result in a sum of 10. The pairs that give a sum of 10 are (4,6), (5,5), (6,4). There are 3 outcomes that give a sum of 10.
Calculate Favorable Outcomes: Adding the number of outcomes for a sum of 3 and a sum of 10, we get 2+3=5 favorable outcomes.
Find Probability: To find the probability, we divide the number of favorable outcomes by the total number of possible outcomes. The probability is therefore 365.
