The probability of picking blue is stated as 2/10 which can be reduced to 1/5
multiply the number of times they pick a marble ( shown as 200) by the probability of picking a blue one ( 1/5)
200 x 1/5 = 200 / 5 = 40
Quinn can expect to pick blue 40 times
It doesn’t matter how many times she rolls the dice. she will have a 1/6 chance is rolling the number 4, which is a 16.6% chance
