Answer

Explanation:

Step1: Count total sections and non - elephant sections

The spinner has 8 sections in total. There are 5 sections with elephants, so there are (8 - 5=3) non - elephant sections.

Step2: Assume a number of spins

Let's assume the spinner is spun 240 times (a common number for probability problems when the denominator of the probability fraction is 8).

Step3: Calculate the expected number of non - elephant landings

The probability of not landing on an elephant is (\frac{3}{8}). If the spinner is spun (n = 240) times, the expected number of times it will not land on an elephant is (n\times\frac{3}{8}=240\times\frac{3}{8}=90).

Step4: Consider the nature of probability

Probability gives an expected value. In real - world spins, we expect the result to be close to the calculated value but not exactly the same due to randomness.

Answer:

B. Close to 90 times but probably not exactly 90 times
