A bag contains 4 marbles,6 green marbles, and 2 red. you select one ball by random. What is P red?
Komok [63]

p(outcome) = (number of desired outcomes)/(total number of outcomes)

The total number of outcomes is the sum of the numbers of the marbles.

4 + 6 + 2 = 12

The desired outcome is selecting a red ball. There are 2 red balls, so the number of desired outcomes is 2.

p(red) = 2/12 = 1/6
