Question

Maddi plays a game in which she spins a spinner over and over again. The spinner has 4 equally sized sections labeled A, B, C, and D. Spinning a C seven times means the game is over.

Maddi uses a uniform probability model to predict the number of times the spinner will be spun before the letter C appears 7 times.

What is Maddi's prediction for the number of total spins before the letter C appears 7 times?


12 spins

16 spins

21 spins

28 spins

Answer 1

The spinner illustrates probability, and it is expected that the number of spins is 28

How to determine the expected number of vowels?

In the spinner, we have:

Sections = 4

Letter C = 1

Expected appearance = 7

The expected number of letter C is calculated using

Expected = Letter C/Sections * Number of spins

This gives

7 = 1/4 * Spins

Multiply both sides by 4

Spins = 28

Hence, it is expected that the number of spins is 28
