Question

A spinner is divided into 5 equally sized segments colored blue, green, black, red, and yellow. Suppose you spin the wheel once and then spin it again. What is the probability of landing on the color red both times? Give your answer as an exact fraction and reduce the fraction as much as possible.

Answer 1

The probability of landing in any colour is:

`(1)/(5)`

so if we want to get a red, both times, we to multiply 1/5 twice

`(1)/(5)\cdot(1)/(5)=(1)/(25)`

so, the probability of getting red twice is 1/25
