Answer to Question #23976 in Combinatorics | Number Theory for leslie Richmond

Question

A donut crate has 100 apple fritters, 150 chocolate fritters, 200 apple bars and 250 chocolate bars. Choose one at random. What is the probability it is a fritter or contains chocolate?

Answer 1

The number of fritter or containing chocolate is 100+150+250=500.
The total number of items is 100+150+200+250=700.
The probability of choosing a fritter or containing chocolate is: P=500/700=5/7 or approximately 71.4%
