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

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
