Probability of independent and dependent events

Full solution

Q. Three coins are simultaneously flipped, what is the probability that it lands exactly one head

Coin Flip Outcomes: There are $2$ possible outcomes for each coin flip: heads (H) or tails (T).
Total Possible Outcomes: For three coins, the total number of possible outcomes is $2^3 = 8$ .
Favorable Outcomes for One Head: The favorable outcomes for exactly one head are: $HTT$ , $THT$ , $TTH$ .
Counting Favorable Outcomes: Count the favorable outcomes: there are $3$ ways to get exactly one head.
Calculating Probability: Calculate the probability: Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{3}{8}$ .
