Question

A spinner is half red and half blue. If you spin the spinner twice, what is the probability that you will get red both times?

Answer 1

Answer: Probability of getting red both times is
`(1)/(4)`

Explanation:

Since we have given that

A spinner is half red and half blue.

Probability of getting red is given by

`(1)/(2)`

Probability of getting blue is given by

`(1)/(2)`

Since he spins the spinner twice.

Probability that you will get red both times is given by

`(1)/(2)* (1)/(2)\\\\=(1)/(4)`

Hence, Probability of getting red both times is
`(1)/(4)`
