A)

150 were surveyed, possible outcomes, and 132 said they prefer dogs, favorable outcomes,   132/150 or 22/25 or 0.88, now 0.88 * 100 is just 88, namely 88% is the probability.

b)

since we know is 88%, what is 88% of 100?  (88/100) * 100, 0.88 * 100, or just 88 students.

c)

18/150 or 3/25 or 0.12 namely 12%,

what's 12% of 300?  (12/100) * 300, or 0.12 * 300, so just 36 students.

<h3>Answer:  8</h3>

Reason:

Replace p with 2 and evaluate.

Think of a cube that is 2 units along each side. It's volume is 2*2*2 = 8 cubic units. Repeated multiplication can be shortened to using exponents.

Another example: 7^4 = 7*7*7*7
