You are flying out of Terminal 3 at JFK on a Wednesday afternoon between 3:00 and 4:00 PM. You get stuck in a traffic jam on the way to the airport,
and if it takes you longer than 12 minutes to clear security, you'll miss your flight. The probability that you'll miss your flight is
You have arrived at the airport and have been waiting 10 minutes at the security checkpoint. Recall that if you spend more than 12 minutes clearing
security, you will miss your flight. Now what is the probability that you'll miss your flight?

onsider a random variable x that follows a uniform distribution, with a = 2 and b = 9.
What is the probability that x is less than 6?
P(x < 6) = 0.2857
P(x < 6) = 0.5714
P(x < 6) = 0.17142
P(x < 6) = 0.4286
What is the probability that x is between 4 and 6?
P(4 ≤ x ≤ 6) = 0.2857
P(4 ≤ x ≤ 6) = 0.157135
P(4 ≤ x ≤ 6) = 0.0928525
P(4 ≤ x ≤ 6) = 0.11428
Consider a random variable x that follows a uniform distribution, with a = 8 and b = 14.
What is the probability that x is less than 13?
P(x < 13) = 0.1667
P(x < 13) = 0.41665
P(x < 13) = 0.24999
P(x < 13) = 0.8333
What is the probability that x is between 11 and 12?
P(11 ≤ x ≤ 12) = 0.0541775
P(11 ≤ x ≤ 12) = 0.1667
P(11 ≤ x ≤ 12) = 0.06668

- please solve this problem step by step and make it quick pleasearrow_forwardWHAT IS THE CORRECT ANSWER AND WHY?arrow_forwardA common way for two people to settle a frivolous dispute is to play a game of rock-paper-scissors. In this game, each person simultaneously displays a hand signal to indicate a rock, a piece of paper, or a pair of scissors. Rock beats scissors, scissors beats paper, and paper beats rock. If both players select the same hand signal, the game results in a tie. Two roommates, roommate A and roommate B, are expecting company and are arguing over who should have to wash the dishes before the company arrives. Roommate A suggests a game of rock-paper-scissors to settle the dispute. Consider the game of rock-paper-scissors to be an experiment. In the long run, roommate A chooses rock 21% of the time, and roommate B chooses rock 61% of the time; roommate A selects paper 39% of the time, and roommate B selects paper 21% of the time; roommate A chooses scissors 40% of the time, and roommate B chooses scissors 18% of the time.

- A qualifying exam for a graduate school program has a math section and a verbal section. Students receive a score of 1, 2, or 3 on each section. Define X as a student’s score on the math section and Y as a student’s score on the verbal section. Test scores vary according to the following bivariate probability distribution. y 1 2 3 1 0.22 0.33 0.05 x 2 0.00 0.08 0.20 3 0.07 0.05 0.00 μXX = , and μYY = σXX = , and σYY = The covariance of X and Y is . The coefficient of correlation is . The variables X and Y independent. The expected value of X + Y is , and the variance of X + Y is .
