(Remember that you need to consider the otherrows of students, not just the front row.)There are _____________ seating arrangements thatput them in the front seats.b. What is the probability that Larry, Moe, Curly and Shemp aresitting in the front seats?The probability is ______________ Round your answer to4 decimal places.
2. You own 15 CDs.You want to randomly arrange 4 of them in a CD rack.What is the probability that the rackends up in alphabetical order?Round your answer to 6 decimal places.
3. A jury pool has 21 men and 23 women, from which 12jurors will be selected.Assuming that each person is equally likely to be chosen and thatthe jury is selected at random, find the probability that the juryconsists of the following. Round your answers to 8 decimalplaces.all men: _________all women:________ 7 men and 5 women :_______6 men and 6 women: __________
