Everyone buying a pizza at JR's pizzeria gets a card that conceals either a J or an R. When the waxcovering is rubbed off, the chance is 90% that a J will appear. Different cards can be treated as havingindependent letters.Once a person has both a J and R, she is entitled to a free pizza. Note that, because the same letter cancome up on several successive purchases, that rule is not equivalent to one free pizza per two paid ones.If Pamela starts patronizing the pizzeria, find the probability that:a) She receives an R on her first purchase.b) Her first two purchases yield a J and R, in that order.c) She is eligible for a free pizza after her first two purchases.d) It takes her exactly three purchases to earn a free pizza.

Assume that the standard deviation price per gallon is $0.07 per gallon and use Chebyshev's inequality to answer the following. (a) What percentage of gasoline stations had prices within 4 standard deviations of the mean? (b) What percentage of gasoline stations had prices within 1.5 standard deviations of the mean? What are the gasoline prices that are within 1.5 standard deviations of the mean? (c) What is the minimum percentage of gasoline stations that had prices between $3.22 and $3.64?

The next generation of miniaturized wireless capsules with active locomotion will require two miniature electric motors to maneuver each capsule. Suppose 10 motors have been fabricated but that, in spite of tests performed on the individual motors, 2 will not operate satisfactory when placed in a capsule. To fabricate a new capsule, 2 motors will be randomly selected(that is, each pair of motors has the same chance of being selected.) Find the probability that: A: Both motors will operate satisfactory in the capsule. B:One motor will operate satisfactory in the capsule and one will not.
