Question

in one town, 45% of all voters are democrats. if two voters are randomly selected for a survey, find the probability that they both are democrats.

Answer 1

Explanation:

Probability is 45% x 45%.

that is 45/100 x 45/100 = 2025/10000

You would multiply by 100 to express as a percentage, so:

2025/10000 x 100 = 2025/100

= 20.25%
