A spinner is spun and a die is rolled. What is the probability
of spinning red with the spinner or rolling an odd number with the
die.
red
/yellow
blue
green

Answer 1

The probability of spinning red with the spinner or rolling an odd number with the die is
`(1)/(8)`

Step-by-step explanation:

Given that,

Total color in spinner = 4

Let the area of four parts is equal in the spinner.

We need to calculate the probability of spinning red

Using formula of probability

`P(A) = (Number\ of\ red\ color\ outcome)/(Total\ number\ of\ colors\ in\ the\ spinner)`

Put the value into the formula

`P(A)=(1)/(4)`

We need to calculate the probability of odd number of the die

Using formula of probability

`P(B) = (Number\ of\ odd\ digits\ outcome)/(Total\ number\ of\ digits\ in\ the\ die)`

Put the value into the formula

`P(B)=(3)/(6)`

`P(B)=(1)/(2)`

We need to calculate the probability of spinning red with the spinner or rolling an odd number with the die

Using formula of probability of two events which is independent

`P(A\ and\ B)=P(A)* P(B)`

Put the value into the formula

`P(A\ and\ B)=(1)/(4)*(1)/(2)`

`P(A\ and\ B)=(1)/(8)`

Hence, The probability of spinning red with the spinner or rolling an odd number with the die is
`(1)/(8)`
