i) Yellow colour
ii) Black colour
iii) Red colour
iv) White colour​

Answer 1

Answer:

1, 10/30=1/3

2, 8/30=4/15

3, 5/30=1/6

4, 7/30

Step-by-step explanation:

Probability, (P) of Event E=

P(E)=(number of favorable outcomes)/(total number of outcomes)

Answer 2

Answer:

i) p( getting yellow colour ball)= 10/30= 1/3

ii) P(getting black colour ball)= 8/30=4/15

iii) P(getting red colour ball)= 5/30= 1/6

iv) P(getting white colour ball) = 7/30
