Please help and explain how In a raffle, the winners of the first and second prizes each receive one ticket to an upcoming concert. You and a friend each buy a raffle ticket along with 12 other people. What is the exact probability that you win the first prize and your friend wins the second prize?

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
