Computer plot on the same axes the normal density functions with μ=0σ=1and, 2, and 5. Label each curve with itsσ.

Short Answer

Expert verified

The first, second and third curves are symmetric across the vertical axis but have different limits.

The graph is given below

Some transistors of two different kinds (call them N and P) are stored in two boxes. You know that there are 6 N’s in one box and that 2 N’s and 3 P’s got mixed in the other box, but you don’t know which box is which. You select a box and a transistorfrom it at random and find that it is an N; what is the probability that it came from the box with the 6 N’s? From the other box? If another transistor is picked from the same box as the first, what is the probability that it is also an N?

Set up an appropriate sample space for each of Problems 1.1 to 1.10 and use itto solve the problem. Use either a uniform or non-uniform sample space or try both.

A trick deck of cards is printed with the hearts and diamonds black, and the spadesand clubs red. A card is chosen at random from this deck (after it is shuffled). Findthe probability that it is either a red card or the queen of hearts. That it is eithera red face card or a club. That it is either a red ace or a diamond.

In paying a bill by mail, you want to put your check and the bill (with a returnaddress printed on it) into a window envelope so that the address shows right sideup and is not blocked by the check. If you put check and bill at random into theenvelope, what is the probability that the address shows correctly?

(a) There are 10 chairs in a row and 8 people to be seated. In how many ways can this be done?

(b) There are 10 questions on a test and you are to do 8 of them. In how many

Ways can you choose them?

(c) In part (a) what is the probability that the first two chairs in the row are vacant?

(d) In part (b), what is the probability that you omit the first two problems in the

test?

(e) Explain why the answer to parts (a) and (b) are different, but the answers to

(c) and (d) are the same.
