Which of the following has a quotient of 5? A. –75 ÷ 15 B. 12 ÷ 2 C. 30 ÷ –6 D.

A

Step-by-step explanation:

75÷ 15=5

a) 0.0289

b) 0.289

c) 0.0048

Step-by-step explanation:

16 bottles total

9 Brand A

7 Brand B

5 bottles selected

(a) What is the probability that all five are brand A?

Total: ₁₆C₅ = 4368

5 bottles brand A

₉C₅ = 126

126/4368 = 0.0289

(b) What is the probability that exactly two are brand A?

Total: ₁₆C₅ = 4368

2 of Brand A: ₉C₂ = 36

3 of Brand B: ₇C₃ = 35

As we have 2 of A AND 3 of B = 36*35 = 1260

1260/4368 = 0.289

(c) What is the probability that none is brand A?

Total: ₁₆C₅ = 4368

5 of Brand B: ₅C₇ = 21

21/4368 = 0.0048
