A box of chocolates contains 5 milk chocolates, 4 dark chocolates, and 3 white chocolates. What is the probability that you randomly select a milk chocolate first, replace it, and then select a white chocolate? *

Answer:

10.42% probability that you randomly select a milk chocolate first, replace it, and then select a white chocolate

Step-by-step explanation:

Since the chocolate is replaced, the first selection and the second are independent of each other.

Independent events:

If two events, A and B, are independent.

[tex]P(A \cap B) = P(A)P(B)[/tex]

In this question:

Event A: Selecting a milk chocolate first.

Event B: Selecting a white chocolate.

5+4+3 = 12 chocolates. Of those, 5 are milk.

This means that [tex]P(A) = \frac{5}{12}[/tex]

3 are white.

This means that [tex]P(B) = \frac{3}{12} = \frac{1}{4}[/tex]

What is the probability that you randomly select a milk chocolate first, replace it, and then select a white chocolate?

[tex]P(A \cap B) = P(A)P(B) = \frac{5}{12}*\frac{1}{4} = \frac{5}{48} = 0.1042[/tex]

10.42% probability that you randomly select a milk chocolate first, replace it, and then select a white chocolate
