Question

Margo is going to spin the following spinner 210 times. the spinner is divided into equal sections. a circle has seven equal sections. there is a monkey in one section, a mouse in two sections, and an elephant in four sections. the arrow of the spinner points at a mouse section. a circle has seven equal sections. there is a monkey in one section, a mouse in two sections, and an elephant in four sections. the arrow of the spinner points at a mouse section. what is the best prediction for the number of times the spinner will not land on an elephant?

O exactly 90 times
O close to 90 times but probably not exactly 90 times
O exactly 120 times
O close to 120 times but probably not exactly 120 times

Answer 1

The best prediction for the number of times the spinner will not land on an elephant is close to 90 times but probably not exactly 90 times.

Step-by-step explanation:

To find the best prediction for the number of times the spinner will not land on an elephant, we need to calculate the probability of not landing on an elephant after each spin.

The probability of landing on an elephant is 4 out of 7 (since there are 4 elephant sections out of 7 total sections). So, the probability of not landing on an elephant is 1 - (4/7), which simplifies to 3/7.

Since the spinner will be spun 210 times, we can predict that the spinner will not land on an elephant approximately 3/7 of the time. This is close to 90 times but probably not exactly 90 times.

By calculating the probability of not landing on an elephant (3/7) after each spin, we predict that, out of 210 spins, the spinner will likely not land on an elephant around 90 times, providing a close estimation.
