Question

A box has 3red 8white and 4greenballs.what ball is picked at random.find the probability of getting
1. a red ball
2. not a green ball

Answer 1

Answer:total outcome s-3+8+4=15

Probability of red=3/15

Probability of green=4/15

Probability of not getting green=1-4/15=15-4/15=11/15

Step-by-step explanation:

Answer 2

number of red ball = 3

number of white ball = 8

number of green ball = 4

total number of balls = 3+8+4 = 15

1.a red ball = number of red ball / total number of balls = 3/15

not a green ball = number of red and white ball / total number of balls = 8+3 /15 = 11 / 15
