What is the probability of drawing a second white card, given that the first card is white?

P (two white cards)  = P(white on first draw) * P (white on second draw)

 

14 / 95   =   2 / 5   *   P (white on second draw)

 

Multiply both sides by 5/2

 

(5/2)(14/95)   = P (white on second draw)   = 70 / 190   =   7 / 19
