A painter has four different jars of paint colors available, exactly one of which is purple. She wants to paint something abstract, so she blindfolds herself, randomly dips her brush, and paints on the canvas. She continues trying paint jars until she finally gets some purple onto the canvas (her assistant will tell her when this happens). Assume that she does not repeat any of the jars because her assistant removes a jar once it has been used. a. How many outcomes are in the sample space? What are they?
b. How many different events are there?
c. Another painter borrows the four jars of paint and performs the same experiment; i. e., selects paint at random, but she allows the jars to be reused, perhaps over and over many times (assume each contains an unlimited amount of paint). List a few of the outcomes in the sample space, when repetitions are allowed.
d. In the scenario from part c, write an expression for the sample space.
