The probability of choosing two orange balls without replacement is 1/35, and the probability of choosing one orange ball is 1/5.

What is the probability of drawing a second orange ball, given that the first ball is orange?

1/7

11/75

2/7

1/6

answer is 1/7

Step-by-step explanation:

Given that there were some orange balls in a bag.

The probability of choosing two orange balls without replacement is 1/35, and the probability of choosing one orange ball is 1/5.

We have to find out the probability of drawing a second orange ball, given that the first ball is orange

Let A - I ball orange

B = II ball orange

Then P (AB) = 1/35 (given)

P (A) = 1/5 (given)

The probability of drawing a second orange ball, given that the first ball is orange = P (B/A)

=P (AB) / P (A)

= 1/35 divided by 1/5

= 1/7

answer is 1/7
