Answer: d.16 days

Step-by-step explanation:

Hi, using  PERT technique we can calculate the mean by applying the next formula:

Mean = (a + 4m + b)/6

Where:

a = optimistic time

m = most likely time

b = pessimistic time

Replacing with the values given:

Mean = (12 +4 (15) + 24)/6

Solving

m = (12+ 60+24)/6

m= 96/6

m = 16 days

Feel free to ask for more if needed or if you did not understand something.

Using the Fundamental Counting Theorem, we have that:

4. 1,757,600 different license plates can be there.

5. 676,000,000 different driver's license numbers can be formed.

<h3>What is the Fundamental Counting Theorem?</h3>

It is a theorem that states that if there are n things, each with n_1, n_2, \cdots, n_n ways to be done, each thing independent of the other, the number of ways they can be done is:

N = n_1 \times n_2 \times \cdots \times n_n

For the letters there are 26 outcomes and for the digits there are 10 outcomes, hence the parameters for item 4 are given as follows:

n_1 = n_2 = 26, n_3 = n_4 = 10, n_5 = 26

Hence the number of license plates is given by:

N = 26 x 26 x 10 x 10 x 26 = 1,757,600.

For item 5, the parameters are:

n_1 = n_2 = 26, n_3 = n_4 = n_5 = n_6 = n_7 = n_8 = 10

Hence the number of license numbers is:

26 x 26 x 10 x 10 x 10 x 10 x 10 x 10 = 676,000,000
