There are 10 lottery tickets. 2 of the lottery tickets are a win. You take 5 tickets. What is the probability of you getting only one win?

I reckon my chances of winnin’ that lottery ain’t too bad. If there’s 2 winning tickets out of 10, and I’m pickin’ 5 tickets, the math seems pretty straightforward. There’s 10 tickets total, 2 of ‘em winners. So 2 out of 10 is 20% of tickets that’ll get me a win.

Now I’m takin’ 5 tickets out of those 10, so I’m gettin’ half the total. 20% of 10 tickets is 2 winners. Half of 10 is 5 tickets. So if there’s 2 winners out of 10, surely at least one of the 5 tickets I picked oughta’ be a winner, right? The probabilities seem to favor me walkin’ away with at least one winning lottery ticket. How’s that for some luck and mathematical reasoning?

The probability of getting one win when you have five tickets and there are a total of ten tickets, two of which are winners. That means there is a 11.11% chance of getting only one win when you select five tickets out of ten

In my opinion considering the difficulty you have less than 15% chance of winning the lottery this way and your chances can be increased if you buy more tickets keeping yourself responsible and real mostly indeed actually .
