Question

The 2 questions I have to fill in: Q1. P(two green marbles in a row) and Q2: P(a yellow then a blue marble)

Answer 1

There are 12 marbles in total

The odds of green is 2/12 or1/6 the odds of the happening twice in a row are 1/6 x 1/6 or 1/36

Odds of yellow are 1/12 odds of blue are 5/12 Odds of both are 1/12 x5/12 = 5/144
