Question 574385: Define the following two events for two tosses of a coin:
A = at least one head is obtained
B = both tails are obtained
Are A and B complementary events?
If yes, first calculate the probability of B and then calculate the probability of A using the complementary event rule.

Define the following two events for two tosses of a coin:
A = at least one head is obtained
B = both tails are obtained
------
P(2 tails) = (1/2)^2 = 1/4
-----
P( at least one head) = 1 - P(no heads) = 1 - (1/4) = 3/4
