Question

A Bag contains 5 red bolls, 4 green balls and 7 black bolls ,If one boll is draw at random find the probability that 1) Black 2) Red

Answer 1

1)7/16 2)5/16

Step-by-step explanation:

1) total No. of balls =5+4+7=16

total No. of black balls =7

p(E) = total No. of black balls/total No. of balls

=7/16

2)total No. of balls =5+4+7=16

total No. of red balls=5

p(E)=total No. of red balls/total No. of balls

=5/16
