The game called Lotto sponsored by the Louisiana Lottery Commission pays its largest prize when a contestant matches all 7 of the 38 possible numbers. Assume there are 38 ping-pong balls each with a single number between 1 and 38. Any number appears only once, and the winning balls are selected without replacement.

a.	The commission reports that the probability of matching all the numbers are 1 in 12,620,256. What is this in terms of probability?(Round your answer to 8 decimal places.)

b.

Use the hypergeometric formula to find the probability of matching all 7 winning numbers. The lottery commission also pays if a contestant matches 5 or 6 of the 7 winning numbers. Hint: Divide the 38 numbers into two groups, winning numbers and nonwinning numbers.(Round your answer to 8 decimal places.)

Probability

c.	Find the probability, again using the hypergeometric formula, for matching 5 of the 7 winning numbers.(Round your answer to 8 decimal places.)

Probability

d.	Find the probability of matching 6 of the 7 winning numbers.(Round your answer to 8 decimal places.)
