A teacher distributes randomly the 17 papers to her 17 students.
a)What is the probability that each student gets HIS paper?
Probability 16 get their correct paper: (1/2)^17= 0.000007629...
---------------------------------------------------------------------
b)What is the probability that ONLY Steven gets his paper?
P(1 right) = 17C1(1/2)^1(1/2)16) = 17*answer to "a" = 0.00012970...
