Answer:
1. total number of balls in the bag = 3+5=8
number of red balls = 3
probability of getting red ball = Number of red balls /Total number of balls
= 3/8
2. total number of balls in the bag =8
probability of not getting a red ball
= probability of getting black balls
= Number of black balls/ Total number of black balls
= 5/8
