Everything printed in the Daily Screamer is in (1) boldface or (2) italics or (3) both boldface and italics. In today’s edition, I notice that if something is in boldface, then the chances of it also being in italics is 30%. Moreover, if something is in italics, then the chances of it also being in boldface is 20%. What is the probability that something in the Daily Screamer is in boldface?

2. Let us define a new variable Y = the sum of two dice. Complete both the probability and cumulative probability tables for Y. (Hint: First think about what values Y can take on, and then notice rolling a die produces 6 outcomes but rolling two dice produces 36 outcomes. The following table can help you enumerate all 36 outcomes and find out what is the associated Y value for each outcome.) 1 2 3 4 5 6 1 Y=2...

A sample of the parts is taken from each shift (1, 2, or 3) in a manufacturing operation to investigate the relationship between the shift and the quality of parts (conforming or nonconforming) being produced. The number of conforming and nonconforming parts per shift is summarized in the table below: Shift 1 Shift 2 Shift 3 Total Conforming 370 285 175 830 Nonconforming 30 15 25 70 Total 400 300 200 900 What is the probability a randomly chosen part...

Suppose that five 4-sided dice are rolled, with the numbers 1, 2, 3, and 4 being the equally-likely outcomes for each die. What is the probability that at least two of them result in the outcome 1 and at least two of them result in the outcome 2? (I suggest that you make use of a multinomial distribution to obtain the answer.)

Five identical bowls are labeled 1, 2, 3, 4, and 5. Bowl i contains i white and 5 − i black balls, with i = 1, 2,    , 5. A bowl is randomly selected and two balls are randomly selected (without replacement) from the contents of the bowl. Given that both balls selected are white, what is the probability that bowl 5 was selected?
