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>

Answer:
2x=10
Step-by-step explanation:
7x-14=21
x=5
2x=10 (divide both sides by two)
