Question

Heather has a bag of 15 red, 11 orange, 9 yellow, 12 green, 6 blue and 11 purple markers. how many times would you expect heather to pick a red marker if she picked a marker 90 times?

Answer 1

15 red out of 64 total markers
15 / 64 = .234375
90 x .234375 = 21.09375
so she will pick a red marker about 21 times
