Question

A bag contains 4 red,5black and 6 white balls.A ball drawn at rendim. what is the probability that the ball drawn is red ir white .​

Answer 1

Answer:

probability=no of item/total

total no. of balls=4+5+6=15

no. of red and white balls =4+6=10

so probability of getting red or white ball is

10/15=2/3

so 2/3

Answer 2

ANSWER

P(E) that the ball drawn is red or white =sum of red ball +white ball /total no. of balls

total balls=15

P(E)=4+6/15

P(E)=10/15

p(E)2/3
