A certain disease only affects men 20 years of age or older. The chart shows the probability that a man with the disease falls in the given age group. What is the probability that a randomly selected man with the disease is not between the ages of 55 and 64?
0.68

There are 34 chocolates in a box, all identically shaped. There 12 are filled with nuts, 8 with caramel, and 14 are solid chocolate. Someone randomly selects one piece, eats it, and then selects a second piece. Find the probability of selecting 2 nut candies. Express your answer as a simplified fraction

single 6-sided die is rolled twice. The set of 36 equally likely outcomes is {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (6,1), (6,2), (6,3), (6,4), (6,5), (6,6)}. Find the probability of getting two numbers whose sum is greater than 10.

The table to the right represents a random sample of the number of deaths per 100 cases for a certain illness over time. If a person infected with this illness is randomly selected from all infected people, find the probability that the person dies 3-4 years after diagnosis. Express your answer as a simplified fraction and as a decimal. 3-4ys=35

A probability experiment is conducted in which the sample space of the experiment is S={3,4,5,6,7,8,9,10,11,12,13}. Let event A={6,7,8,9,10}. Assume that each outcome is equally likely. List the outcomes in Ac. Find P(Ac).
