Question

The probability of drawing two white cards, without replacement is 14/95, and the probability of drawing one white card is 2/5. What is the probability of drawing a second white card, given that the first card is white?

Answer 1

Answer: 7/19

Explanation:

Given that:

Probability of drawing 2 white cards without replacement = 14 / 95

Probability of drawing one white card = 2/5

Probability of drawing a second white card Given the first card is white will be :

P(2 white cards without replacement) = p(one white card) * p(second white card)

14 /95 = 2/5 * p

P = 14/95 ÷ 2/5

P= 14/95 * 5/2

P = 70 / 190

P = 7/ 19
