Question

a bag contains 10 red 5 blue and 7 green balls a ball is drawn at random find the probability of all not blue ball and white ball​

Answer 1

Answer:

total no. of balls 10+7 +5 = 22

p(e) of white ball = 0

Answer 2

Answer:

in bag

red balls - 10

blue balls -5

green balls - 7

given that find probability of all not blue ball and white ball

so blue balls + white balls = 7

so in total there are 22 balls

so probability = 15/ 22
