(1 point) A man and a woman agree to meet at a cafe about noon. If the man arrives at a time uniformly distributed between 11 : 40 and 12 : 15 and if the woman independently arrives at a time uniformly distributed between 11 : 50 and 12:40, what is the probability that the first to arrive waits no longer than 10 minutes?

Problem #4: A man and woman agree to meet at a certain location at 12:33 pm. If the man arrives at a time that is uniformly distributed between 12:21 pm and 12:46 pm, and if the woman arrives independently at a time that is uniformly distributed between 12:00noon and 1:00 pm, what is the probability that the man arrives first?

A group of 10 people agree to meet for lunch at a cafe between 12 noon and 12:15 P.M. Assume that each person arrives at the cafe at a time uniformly distributed between noon and 12:15 P.M., and that the arrival times are independent of each other. Jack and Jill are two members of the group. Find the probability that Jack arrives less than two minutes before Jill.

Problem Six (Continuous Joint Random Variables)
(A) Suppose Wayne invites his friend Liz to brunch at the Copley
Plaza. They are coming from separate locations and agree to meet in
the lobby between 11:30am and 12 noon. If they each arrive at
random times which are uniformly distributed in the interval, what
is the probability that the longest either one of them waits is 10
minutes?
Hint: Letting ? and ? be the time each of them arrives in
minutes...

P2.10 Interview question Two people, trying to meet, arrive at times independently and uniformly distributed between noon and 1pm. Find the expected length of time that the first waits for the second. Problem 4 Do P2.10. Apply the bottom formula on P2.8. If we measure time in hours starting from noon, then each arrival time is uniformly distributed in [0,1], so the joint density of the two arrival times (x, y) is/(x, y) 1 for 0 s x s 1,0...

Two people, trying to meet, arrive at times independently and
uniformly distributed between noon and 1pm. Find the expected
length of time that the first waits for the second.Here
is the "bottom formula"
Apply the bottom formula on P2.8. If we measure time in hours starting from noon, then each arrival time is uniformly distributed in [0,1], so the joint density of the two arrival times (X,Y) is f(x,y) = 1 for 0 sx S1,0 sys 1. How to express...

UUUIUITULLUTULIUI Previous Problem List Next (1 point) The rates of on-time flights for commercial jets are continuously tracked by the U.S. Department of Transportation. Recently, Southwest Air had the best rate with 70 % of its flights arriving on time. A test is conducted by randomly selecting 10 Southwest flights and observing whether they arrive on time. Find the probability that exactly 4 flights arrive on time. Preview My Answers Submit Answers
