Question

a bag contains 15 balls some of them are wild some Bablu and summer get the number of white balls is 11 times the number of Globus the number of red balls is less than the number of white balls also the number of red balls is more than the number of Blue Balls if one ball is selected at random from the bag what is the probability that it is red

Answer 1

Answer:

P(red. Ball) = 15-x/ 15

P(blue ball)= x/15

Q

When five ball are added

P(re d)= 20-x/20

P( blue)= x+5/20

According to question

2(15-x/15)= 20-x/20

300=25x

12=x

Substitute this in p of blue when 5 balls are added

P(blue)= 12+5/20=17/20
