WebJan 16, 2024 · Solution: To calculate the probability of event, by flipping of two coins, At least two Heads. Atmost one Heads and on tail. Probability of having two Heads P (A) = Favorable outcomes / Total number of outcomes. Probability of At least one Tail and one head P (A) = Favorable outcomes / Total number of outcomes. WebGiven a fair coin is flipped 5 times. Total sample space while tossing a coin 5 times is 2 5 = 32. Let P be the probability of getting exactly 3 tails. We can calculate by using binomial expansion. 5 C 3 = 5!/ (3!2!) = 10 ways to get exactly 3 tails. P (exactly 3 tails) = 10/32. = 5/16. The probability of getting exactly 3 tails is 5/16.
