anyone help! :) 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: Color of Marble Number of Times Rolled Blue 16 Green 20 Yellow 14 Heads Tails 18 32 Using Shyla's simulation, what is the probability of pulling a blue marble and the coin landing tails up?

    chance of pulling a blue marble is 16/50 and chance of a coin landing tails up is 32/50. I think to finish the problem it would be 16/50*32/50

    Because the 2 events are independent you multiply the probabilities

    which i believe in probability you are not supposed to reduce but i could be wrong and np :)
