Question

You toss three fair coins into the air . List the possible outcomes that could result from the loss, determine the probability of no heads, determine the probability of exactly one head, determine the possibility of exactly two heads and last determine the probability of more than one head.

Answer 1

3 coins

P(0H) = 1/8

P(1H) = 3/8

P(2H = 3/8

P(3H) = 1/8

P(2 or 3H) = 1/2
