Answer
0 or 2 heads $P(0)=P(2)=0.25$
1 head $P(1)=0.5$
Work Step by Step
While you should do the experiment by tossing two coins 100 times, record the outcomes, and compute the
empirical probabilities of each, we can use the binomial distribution to predict the results.
$P(x)=nCx⋅p^xq^{n−x}$ where $n=2,x=0,1,2, p=q=0.5$ is the probability of getting a head or tail.
We have $P(0)=P(2)=0.25$ and $P(1)=0.5$
