Answer:

answer is b. 7/19

Step-by-step explanation:

A: event of drawing first white card

P(A)= 2/5

B/A: event of drawing second white card given first white card has been drawn

we have to find P(B/A)

A∩B: event of drawing two white cards without replacement

P(A∩B)=14/95

baye's theorem says that

P(A∩B)=P(A)×P(B/A)

14/95=P(B/A)×2/5

⇒P(B/A)=7/19

hence,<u> answer is b. 7/19</u>
