PLEASE HELP I GIVE 20 POINTS!


Erik is performing a marble experiment in math class. His teacher places an equal number of black, red, and white marbles in a bag. Then, Erik randomly takes out a marble, records the result, and puts the marble back in the bag. Each of the first four times Erik takes out a marble, he gets a black marble.

AWhat is the theoretical probability of Erik picking a black marble next time? Based on Erik's results, what is the experimental probability of Erik picking a black marble next time?
BExplain the difference between the two probabilities you found in part A.
CWhat is the theoretical probability and likelihood of getting four black marbles in a row?

Verified Answer :

I think u should go w/ choice A because u need to find the theoretical probability of Eric picking a black marble.......

Process elimination so... C doesn't make sense D doesn't make sense. So B or a. Go with a.
