Question

A bag contains 6red balls,4 green balls,and3,blue balls if we choose a ball then another one what is the probability That the first ball will be green and the second ball be red

Answer 1

Total balls: 6 + 4 + 3 = 13

First pick green = total green / total balls = 4/13

adter picking the first ball there are 12 balls left.

Picking red = total red/ total balls left = 6/12 = 1/2

probability of picking both = 4/13 x 1/2 = 4/26 = 2/13

answer: 2/13
