Answer 1

Answer:

(i)probability of getting black 5/15 = 1/3

(ii) probability of not blue 9 /15 =3/5

(iii) probability of blue and white 10/15 =2/3

Answer 2

Step-by-step explanation:

probability that the ball is black is

5/15=1/3

Probability that the blue ball isn't black is

1-6/15= 9/15=3/5

Probability that the ball is blue or white is

10/15=2/3

Probability that the ball is blue and white is

2/15
