Discrete Probability Distribution A rough sketch of the graph will be fine.

A bag contains six red marbles, five yellow marbles, and four black marbles. Marbles are selected from the bag, one at a time, without replacement, until four marbles have been taken. a) Identity the type of probability distribution. b) Create a probability distribution for choosing red marbles. Show calculations within the table. c) Graph the distribution. d) Determine the expected number of red marbles
