# What is the probability of winning by getting more heads when flipping a coin once or flipping a coin twice?

Your question is a bit difficult to understand. I will rephrase it as follows:

What is the probability of getting a head if a coin is flipped once?

p = 0.5

What is the probability of getting 2 heads if a coin is flipped twice =

The possible events are HT, TH, HH, TT amd all are equally likely. So the probability of HH is 0.25.

What is the probability of getting at least on head if the coin is flipped twice.

Of the possible events listed above, HT, TH and HH would satisfy the condition of one or more heads, so the probability is 3 x 0.25 = 0.75 or 3/4.

Also, since the probability of TT is 0.25, and the probability of all events must sum to 1, then we calculate the probability of one or more heads to be 1-0.25 = 0.75 Study guides
