3 coins are flipped. What is the probabilty of getting no heads?

Explanation:

Assuming a fair coin, the probability of getting tails is 1/2. The probability of getting three tails in a row is (1/2)^3 = (1/2)*(1/2)*(1/2) = 1/8

Put another way, there are 8 possible outcomes when flipping three coins. Those outcomes are:

We see that only one occurrence of TTT shows up out of the eight possible outcomes; therefore, the probability of getting TTT is 1/8

just get this app called photo math it should be able to do those
