Question

there is 2 spinners. one containing numbers 1,2,3,4,5 and second spinner containing colors: red, red, green, blue

what is the probability of spinning an even number and the color red?


i know there is 2 reds and 2 even numbers so i thought the answer would be 4/9 but its not one of the answers in the choices i have..

possible answers:
1/10

1/5

4/5

3/20

Answer 1

There are two even numbers in the set of five numbers. So the probability of an even number is 2/5.
The probability of red is 2/4.
Therefore the probability of spinning an even number and the color red is given by:
\[\frac{2}{5} \times \frac{2}{4}=\frac{1}{5}\]
