56. Mom has two apples and three pears. Every day for five consecutive days, she gives out one fruit. In how many ways can this be done?
56. Here is one way to distribute apples and pears: 000 'on the 1st and 3rd day - apples, on the 2nd, 4th, and 5th days - pears),

## 000

(on the first three days - pears, on the last two days - apples). Thus, we need to count all the tables with two light and three dark circles; but we have already done this when solving problem 44. The answer is $C_{5}^{2}=10$
