Question

A cooler at a picnic contains 100 cans of soda covered by ice. There are 34 cans of​ cola, 50 cans of orange​ soda, 12 cans of ginger​ ale, and 4 cans of root beer. The cans are all the same size and shape. If one can is selected at random from the​ cooler, determine the probability that the soda selected is root beer​, cola comma or ginger ale.

The probability that the can selected is a root beer​, cola comma or ginger ale is nothing .
​(Type an integer or a simplified​ fraction.)

Answer 1

P = 1/2 = 0.5

Explanation:

Total amount of cans = 100

Cans of cola = 34

Cans of orange soda = 50

Cans of ginger ale = 12

Cans of root beer = 4

Probability of selecting

- a can of cola = 34/100 = 0.34

- a can of orange soda = 50/100 = 0.5

- a can of ginger ale = 12/100 = 0.12

- a can of root beer = 4/100 = 0.04

Since we are asked the probability that the can selected is a root beer​, cola, or ginger ale, we need to add together the probabilities of each.

P = 0.04 + 0.34 + 0.12 = 0.5 = 1/2
