Answer:

answer is 1/7

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
