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