Answer 1

6 pink barrettes

Explanation:

Divide the number of pink barrettes by the total number of barrettes and multiply the quotient by 50 people.

300/2500 Simplified = 3/25 = 0.12

50 people times 0.12 = 6 expected pink barrettes

(hope this helped : ) )

Answer 2

Total no. of buttons = 300 + 700 + 1000

+ 500 = 2500

Possibility for a person to pick a pink button = 300/2500 = (3/25)%

Amount of pink buttons she can expect her friends to pick = 50(3/25) = 6

She can expect to make 6 pink barrettes.

(she sure has a lot of friends...)
