Question

help?

Answer 1

Hi, and welcome to QuestionCove!
So far, the numbers drawn already have been 17, 4, 21, and 5, which each match with one of the 5 numbers chosen. There is only 1 possibility for all 5 numbers to match--if the last number drawn is 39. Out of 75 possible numbers, 4 have been drawn already; since there are no repeats, that leaves 71 possibilities.
So, there is 1 possibility out of 71 remaining equally likely possibilities that all numbers match. Written as a fraction, that's a 1/71 probability, or slightly less than 1.5%

Answer 2

Ohh ok
I was confused and all that cause of the extra numbers..
Thank you!

Answer 3

I see how the extra numbers could make it confusing. It's basically a problem about the chance of randomly picking one option out of many different options.

You could also imagine the problem as a bag containing 75 differently colored marbles and trying to guess which 5 colors you pick. The first 4 colors you pick match your guesses, and the chance of picking the last marble to match your last guess would still be 1/71.

Answer 4

Or, maybe it's easier to imagine if the marbles have different numbers written on them? I hope I'm not making things more confusing :D

Answer 5

It's fine :T
