1: B
because a triangle angles all have to add up to 180
[6, -infinity)
have a good night
Midday is 12pm so you add whatever hours to that. Which is 1:20pm after midday (12pm)
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.
