About Universal
We are asked to find the probability of getting exactly 2 heads in 3 coin tosses. Assuming the coin is fair, the probability of heads (p) = 0.5 and the probability of tails (q) = 0.5. Each toss is independent. This is a binomial probability problem, where: n = number of trials = 3 k = number of desired successes (heads) = 2 p = probability of success = 0.5 q = probability of failure = 0.5 The binomial probability formula is: ๐(๐ heads in ๐ tosses)=(๐๐)โ ๐๐โ ๐๐โ๐ Plugging in the values: ๐(2 heads in 3 tosses)=(32)โ (0.5)2โ (0.5)1=3โ 0.25โ 0.5=0.375 Final Answer: The probability of getting exactly 2 heads in 3 coin tosses is 0.375 or 37.5%.
