Question

A spinner is separated into 3 equal pieces, as shown below: Mary spins the spinner 6 times. What is the theoretical probability that it stops on the red sector on the last spin?
A.) 1/36
B.) 1/9
C.) 1/3
D.) 2/3

Answer 1

Answer:

C. 1/3

Step-by-step explanation:

Given:

Number of colors listed (Successful Outcome)

Red 1

Yellow 1

Purple 1

Total or Possible outcome= 3

Required:

What is the theoretical probability that it stops on the red sector on the last spin?

Formula:

Probability= Successful outcome ÷ Possible outcome

Solution:

Probability of the spinner stoping on red.

Probability= Successful outcome ÷ Possible outcome

Probability=1÷3

Probability=1/3

Hope it helps ;) ❤❤❤

Answer 2

The theoretical probability that spinner stops on the red sector on the last spin is option (C)  $\frac{1}{3}$

What is Probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given,

A spinner is separated into 3 equal parts.

Then Mary spins the spinner 6 times.

What is the theoretical probability that it stops on the red sector on the last spin.  So only last spin is important, outcomes of first 5 spin is not important and it is independent.

Probability = Number of favorable outcome / Number of Total outcome

Probability (Red sector) =  $\frac{1}{3}$

Hence, the theoretical probability that spinner stops on the red sector on the last spin is  option (C)  $\frac{1}{3}$
