A coin has two sides. One side has the number 1 on it and the other side has the number 2 on it. If the coin is flipped four times what is the probability that the sum of the numbers on the landing side of the coin will be greater than 4?
Choose the most appropriate option
A) 3/16 B) 15/16 C) 11/16 D) 5/8 E) 3/4
There are 16 possible outcomes and only one (1111) has a sum equal or less than 4.   P(the sum is greater than 4) = 1 - 1/16 = 15/16   The answer is 15/16.
