If a coin is tossed 3 times what is the probability that it will land either heads 3 times or tails 3 times? Choose the correct option
A) 1/4
B) 1/16
C) 1/2
D) 1/8
E) 1/32
The probability of 3 heads is (1/2)^3 = 1/8   The probability of 3 tails is (1/2)^3 = 1/8   The probability of 3 heads or 3 tails is 1/8 + 1/8 = 1/4   The answer is 1/4.
