The probability of choosing two orange balls without replacement is 135 , and the probability of choosing one orange ball is 15 . 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

The probability of drawing a second orange ball, given that the first ball is orange is 1/7

Step-by-step explanation:

let A be the event of choosing one orange ball and B be the event of choosing second orange ball.

Given  probability of choosing one orange ball is 1/5 i.e. P(A)=1/5

probability of choosing two orange balls without replacement is 1/35

i.e. P(A and B)=1/35

As both events are not independent then probability of drawing a second orange ball, given that the first ball is orange= P(B|A)=P(A and B)/P(A)=

therefore,the probability of drawing a second orange ball, given that the first ball is orange is 1/7.

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
