P(amusement park) = 0.47 , P(water park) = 0.58
P( amusement park OR water park) = 0.75
P( amusement park AND water park) = ?
Using addition rule of probability,
P(A OR B) = P(A) + P(B) - P(A AND B)
0.75 = 0.47 + 0.58 - P( amusement park AND water park)
Therefore,
P( amusement park AND water park) = 0.47 + 0.58 - 0.75
P( amusement park AND water park) = 0.30
Probability that she visits both of the parks on vacation = 0.30

Assume that the amusement park industry is perfectly competitive. Suppose it is in long run equilibruym when the price of roller coaster fuel increases, raising the cost of operating roller coasters. 1. Draw 2 graphs (1 overall market and 1 firm specific) demonstrating what you expect to happen to the number of amusement parks in business. 2. Provide a brief explanation of what is occuring in the graphs.

Many amusement parks base their projections of revenues and profits on the assumption that the average young adult visits an amusement park four times per year. To investigate the validity of this assumption, a random sample of 63 young adults is drawn and each is asked to report the number of times they skied the previous year. The sample yields an average of 4.841 and a sample standard deviation of 2, can we infer that the assumption is wrong with...

4. (30 points) Amia goes grocery shopping at either Kroeger (K), Busch's (B), or Plum Market (P). If she goes to Kroeger today, next time she will either go to Kroeger again with probability 0.2, she will go to Busch's with probability 0.5, or otherwise she will go to Plum Market. If she goes to Busch's today, then she will go to Kroeger, Busch's, or Plum Market next time with probabilities 0.4, 0.2, and 0.4, respectively. If she goes to...

1. A roller coaster at an amusement park has a dip that bottoms out in a vertical circle of radius r. A passenger feels the seat of the car pushing upward on her with a force equal to twice her weight as she goes through the dip. If r = 28.7 m, how fast is the roller coaster traveling at the bottom of the dip? 2. A 0.21-kg ball on a stick is whirled on a vertical circle at a...

Question 2 --/15 View Policies Current Attempt in Progress Thunder Corporation, an amusement park, is considering a capital investment in a new exhibit. The exhibit would cost $152,835 and have an estimated useful life of 6 years. It can be sold for $63,100 at the end of that time. (Amusement parks need to rotate exhibits to keep people interested.) It is expected to increase net annual cash flows by $26,000. The company's borrowing rate is 8%. Its cost of capital...

The local amusement park was interested in the average wait time at their most popular roller coaster at the peak park time (2 p.m.). They selected 13 patrons and had them get in line between 2 and 3 p.m. Each was given a stopwatch to record the time they spent in line. The times recorded were as follows (in minutes;mean = 114.15): 118, 124, 108, 116, 99, 120, 148, 118, 119, 121, 45, 130, 118. What is the range?
