The probability that she gets <em>more than 3 heads</em> is 0.3456.
There are only two possible outcomes for a fliped coin, either it is head, or it is tail. Since the result is independent of each other coins, the binomial distribution will be used.
Given the following parameters:
- x is the number of successes = 5 (coin flipped 5 times)
- n is the number of trials
- p is the probability of success on a single trial = 0.6
Using the binomial distribution formula:
Hence the probability that she gets <em>more than 3 heads</em> is 0.3456.
