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
P(11 ≤ x ≤ 12) = 0.091685

- 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.
