If the pointer lands on a borderline, spin again.If the spinner is spun once, find the probability that the pointer lands in a yellow region.yellowgreenredredgreenyellow

Answer 1

ANSWER

1/4

EXPLANATION

This spinner is divided into 8 equal regions, and there are 2 regions of each color.

If the spinner is spun once, the probability that the pointer lands in a yellow region is the quotient between the number of yellow regions and the total regions in which the spinner is divided,

$P(yellow)=\frac{\#yellow}{total}=\frac{2}{8}=\frac{1}{4}$

Hence, the probability that the pointer lands in a yellow region is 1/4.
