A coin is weighted so that the probability of getting heads is 0.70. If the coin is flipped twice, what is the probability of ge
tting a tail followed by a head?
1 answer:
If the probability of flipping heads is 0.70, the probability of flipping tails is 0.30.
To find probability, you multiply the probability of each factor together:
P = 0.7 * 0.3
P = 0.21 <em>or</em><em> </em>21%
