Question

A basket contains 2 cartons of white milk, 3 cartons of chocolate milk, and 3 cartons of strawberry milk. A carton of milk is pulled out of the carton without replacement. Then another carton of milk is pulled out without replacement. What is the probability of pulling out 1 carton of chocolate milk followed by another carton of chocolate milk?

Answer 1

Answer: 3/8.

Step-by-step explanation: You have to write a fraction with the amounts of milk in the denominator and the amount of chocolate in the numerator.

Answer 2

• 3/28

Explanation:

Total number of cartons:

• 2 + 3 + 3 = 8

Let cm be the chocolate milk, there are 3 cartons of cm.

The probability of the first pull of cm is:

• P(cm) = 3/8

Then we have 7 total left and 2 cm.

The probability of the second cm is:

• P(cm) = 2/7

Now the probability of the two pulls:

• P(cm and cm) = 3/8*2/7 = 3/28
