The empirical probability of a 4 or 5 is
  (count of outcome = 4 or 5)/(count of all outcomes) = (44 +40)/240 = 7/20

The problem statement asks you to assume the outcomes will remain in this proportion going forward. That is, the number of outcomes (n) of 4 or 5 in the next 60 rolls of the number cube is expected to satisfy
  7/20 = n/60

Multiplying that by 60 gives
  n = 60*(7/20) = 21

Selection D is appropriate.

Which of the following is a correct interpretation of the expression -4 - (-7)?
Zielflug [23.3K]

Answer:

D

Step-by-step explanation:

So we have the expression:

-4-(-7)

First, simplify. Two negatives make a positive. Therefore, the -(-7) turns into +7:

-4-(-7)\\=-4+7

When adding on the number line, we move to the right.

Therefore, the correct interpretation is the value 7 digits to the <em>right</em> of -4.

D is the correct answer.

The probability that a customer selects a pizza with mushrooms or pepperoni is , and the probability that the customer selects o
Andrej [43]

Answer:

The probability of the customer selecting both items is 0.04.

Step-by-step explanation:

The complete question is:

The probability that a customer selects a pizza with mushrooms or pepperoni is 0.45, and the probability that the customer selects only mushrooms is 0.32. If the probability that he or she selects only pepperoni is 0.17, find the probability of the customer selecting both items.

Solution:

The information provided is as follows:

P (M) = 0.32

P (P) = 0.17

P (M ∪ P) = 0.45

Compute the probability of the customer selecting both items as follows:

P(M\cup P)=P(M)+P(P)-P(M\cap P)\\\\P(M\cap P)=P(M)+P(P)-P(M\cup P)\\\\=0.32+0.17-0.45\\\\=0.04

Thus, the probability of the customer selecting both items is 0.04.
