Question

Shyla used a probability simulator to pull 3 colored marbles from a bag and flip a coin 50 times. The results are shown in the tables below:

16 blue
20 green
14 yellow

heads 18
tails 32

Using Shyla's simulation, what is the probability of pulling a blue marble and the coin landing tails up?

Answer 1

P(selecting a blue marble) = 16/50 = 8/25

P( getting a tail) = 32/50 = 16/25

The 2 events are independent so you multiply the probabilities:-

Required probability = 8/25 * 16/25 = 108/625

Answer 2

512/2500
