Question 133742: The probability that federal income tax returns will have 0,1, or 2 errors is 0.53, 0.15, and 0.32 respectively. If 10 randomly selected returns are audited, what is the probability that six will have no errors, three will have one error, and one will have two errors?

You can put this solution on YOUR website! The probability that federal income tax returns will have 0,1, or 2 errors is 0.53, 0.15, and 0.32 respectively. If 10 randomly selected returns are audited, what is the probability that six will have no errors, three will have one error, and one will have two errors?
-----------------------------------------
Multinomial Probability:
P = [n!/x1!*x2!*x3!]
Your Problem:
P = [10!/(6!*3!*1!]
P = [4!/6]
P = 4*0.0154
P = 0.0614
