Question

You spin a spinner with 7 equal spaces numbered 1 through 7. What is the probability that the spinner lands

on a 4 or a 6.

Answer 1

P = 28.57%

Explanation:

Probability

The probability of an outcome is defined as the frequency of the number of times the outcome occurs relative to the number of times that it could have occurred.

The equation to calculate the probability is:

`\displaystyle P=(f)/(n)`

Where f is the number of favorable cases and n is the total cases.

The spinner has n=7 equal spaces numbered 1 to 7. We will calculate the probability that the spinner lands on a 4 or a 6.

The set of favorable outcomes is {4,6} which gives a count of f=2.

The required probability is:

`\displaystyle P=(2)/(7)`

P = 28.57%
