Question

A bag contains 2 white balls, 3 red balls and a black ball. if a ball is selected at random, what is the probability that it is (a). not white

(b). red
(c). black​

Answer 1

a) 2/3

b) 1/2

c) 1/6

Explanation:

2 white balls + 3 red balls + 1 black ball = 6 balls all together so then you do the number of balls over 6

Answer 2

P( not white ) =2/3

P ( red)= 1/2

P( black) = 1/6

Explanation:

2 white balls, 3 red balls and a black ball. = 6 balls

P( not white ) = number of balls not white / total = 4/6 =2/3

P ( red) = number of balls that are red/ total = 3/6 = 1/2

P( black) = number of balls that are black/ total = 1/6
