probability of getting a blue ball is
A) 3/8
B) 4
C) 5/8
D) 1/3
7 Angle in a semicircle is​

Answer 1

Answer:

First we have to select a bag and then we will draw a ball.

Probability of selection of both bags is equal =1/2

Now probability of blue ball taken from first bag = ( 1/2) x (3/11)

and probability of blue ball taken from second bag = (1/2) x (4/11)

So probability of blue ball = ( 1/2) x (3/11) + (1/2) x (4/11) = 7/22

Step-by-step explanation:

Answer 2

Answer:

Option D: 1/3

Step-by-step explanation:

Probability = Favourable Outcomes / Total Outcomes

P(Blue Ball) = 8/24

P(Blue Ball) = 1/3
