Question

A coin is flipped 30 times. What is the probability of getting 15 or more heads? Round answer to 4 decimal places.

Answer 1

Answer #1

Here we have an experiment of clipping a coin so p=0.5, further n=30 and it is constant, events are independent and only two outcomes

Hence binomial distribution properties are satisfied

So we will find required probability using binomial distribution
