Question

A deck of cards has three yellow cards and five green cards. One green card is drawn from the deck and not replaced. One more card is randomly drawn. Find the probability that the second card is yellow.

A. 3/8
B. 3/7
C. 15/56

Answer 1

3/7

it used to be 3/8 but when you removed the green card, the total became 1 less because you did not replace the green card

Answer 2

Option B. 3/7

Explanation:

A deck of cards contains yellow cards = 3 and green cards = 5

So total numbers of cards = 3+5 = 8

Now one green card is drawn so numbers of cards left with us = 8-1 = 7

This is true only when this green card was not replaced.

Now the probability to draw second card with color yellow = yellow cards/Total numbers of cards = 3/7

So the answer is Option B. 3/7
