Question

Karin has 13 coins (2 quarters, 6 dimes, 4 nickels, and 1 penny) in a piggy bank. She turns the bank
upside down and shakes the bank until a coin falls out, puts it aside, and the shakes until another coin
falls out.
What is the probability that the first coin is a nickel and the second coin is a quarter?
Select one:
a. 2/30
b. 6/13
c. 2/13
d. 1/8

Answer 1

Using it's concept, the probability that the first coin is a nickel and the second coin is a quarter is:

2/39.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, we have that:

• For the first coin, 4 out of 13 will be nickels.

• For the second coin, considering a nickel was taken with the first coin, 2 out of 12 will be quarters.

Hence the probability will be given as follows:

p = 4/13 x 2/12 = 4/13 x 1/6 = 2/13 x 1/3 = 2/39.
