Question 1206949: On Thursday, September 28, 2006 an 85 year old lady in Etobicoke, Ontario, woke from a dream about winning a lottery, and wrote down the six numbers on a piece of paper. She bought one Lotto 6/49 ticket the day of the dream using the numbers 1,10,18,24,31 and 46. On Friday, she bought another ticket with the exact same numbers. On Saturday, the real numbers were chosen and her two tickets were both winners. There was one other winning ticket in another province. The total jackpot was $24,000,000. Because the lady had two of the winning tickers, she received 2/3 of the jackpot.
a. What is the probability of getting the six correct numbers with one ticket?
b. If two tickets with the same numbers are purchased, what is the probability of one of the two tickets having all six winning numbers?
C. If two tickets with different numbers are purchased, what is the probability of one of the two tickets having all six winning numbers?
d. Is it a good strategy to select the same numbers twice (If one is only guessing)?

.

In a lottery, it can not happen that two tickets have exact the same numbers.

It is PROHIBITED.

The same as two different cars can not have the same plate license numbers.


In real life, this may only happen if one of the tickets is fake  (or  BOTH  tickets are fake).

To the student who posted this question....

Sorry you had to get that absurd response from the other tutor. In a lottery where the player chooses 6 numbers, it is clearly possible that two (or more) people will choose the same set of numbers.

Re-post your question to see if someone here can help you with it.
