Q:
# A box contains six cards numbered 1-6.I draw a card and do not put it back in the box. What is the probability of drawing a 2 and then a even number?

Accepted Solution

A:

Total Number of cards in the beginning = 6

Probability of drawing a card with 2 written on it = 1/6

This card is not placed back and now we have the cards 1,3,4,5 and 6.

So total number of cards = 5

Number of even cards = 2

Probability of picking an even card = 2/5

Probability of drawing a 2 and then a even number = 1/6 x 2/5 = 1/15

Probability of drawing a card with 2 written on it = 1/6

This card is not placed back and now we have the cards 1,3,4,5 and 6.

So total number of cards = 5

Number of even cards = 2

Probability of picking an even card = 2/5

Probability of drawing a 2 and then a even number = 1/6 x 2/5 = 1/15
