Question

A bag contains 4 white, 5 blue and 6 red balls. They are mixed thoroughly and one ball is drawn
at random. Find the probability of
(a) getting a white ball
b) getting a non-red ball
c) getting any colour balt
(d) not getting a blue ball​

Answer 1

Answer:

(a)4/15

(b)3/5

(c)1

(d)2/3

Step-by-step explanation:

white = 4

blue = 5

red = 6

total=4+5+6=15

(a) P(white)=4/15

(b) P(non red)=(4+5)/15  =9/15=3/5

(c) P(any)=1

(d) P(not blue)=(4+6)/15=10/15=2/3
