A candy store has 10 candy bars and 6 suckers A child is all

A candy store has 10 candy bars and 6 suckers. A child is allowed to buy only 4 pieces of candy. What is the probability that the child will pick all 4 candy bars if they were chosen at random?

Solution

There are 16 items here. Thus there are 16C4 = 1820 ways to get 4 items.

There are 10 candy bars. Thus, there are 10C4 = 210 ways to get 4 candy bars.

Thus, the probability is 210/1820 = 0.115384615 [ANSWER]
