The probability of getting that right is 1%2FC%2830%2C5%29

Part B: Pick the two winning numbers, in the correct order, from 1, … , 5.
What is the probability of winning this lottery?
1. If that means that choosing 2 then 4 is not the same as choosing 4 then 2

the probability of getting that right is 1%2FP%285%2C2%29

And the final answer is 1%2FC%2830%2C5%29×1%2FP%285%2C2%29 which is
approximately .000000351

2. If that means that choosing 2 then 4 is the same as choosing 4 then 2

the probability of getting that right is 1%2FC%285%2C2%29

And the final answer is 1%2FC%2830%2C5%29×1%2FC%285%2C2%29 which is
approximately .0000000702
