Lets say I have 2 lottery tickets. Each ticket has a 1 in 4 chance of winning. Whats the chances I will win on both?
If you could show me a formula to achieve the answer, it would be great!
Thank you!

How about the forumla for 3 lottery tickets. Would it be 1/64?

1/4 - chance of winning one lottery ticket
1/4 * 1/4 = 1/16 - the chance of winning to consecutive lottery tickets
The formula is called multiplying. =)
and to win 3 consecutive times it would just be
1/4 * 1/4 * 1/4
This works because each event is independent of the other. If you win or lose with the first ticket it doesn't effect whether you will win or lose with the second ticket

Since they are independent events (as we call them in statistics since the occurrence of each event doesn't affect the other), all you have to do is simply multiply the probability/chance of each event.
In this case, each ticket has a 1/4 chance of winning. Thus the probability of winning on both tickets would be P = (1/4) * (1/4) = 1/16

So you have a 1in4 chance. OK lets see what it looks like
Lose1
Lose2
Lose3
Win
Cool! But now you have a nother 1in4 chance of winning.
Lets organize it with abc instead of 123
Losea
Loseb
Losec
Win
Now lets combined them
Lose1-losea
Lose1-looseb
Lose1-losec
Lose1-win
Lose2-losea
Lose2-looseb
Lose2-losec
Lose2-win
Lose3-losea
Lose3-looseb
Lose3-losec
Lose3-win
Win-losea
Win-loseb
Win-losec
Win-Win
I count 16 combanations and only one win-win
looks like a 1 in 16 chance.
If you ever have trouble with something just THINK about it.
Use logical thinking.
Yah, 4x4 is 16. But logic can solve all problems if you know how to use it.

your chances are 1 in 16.
1/4 * 1/4 = 1/16
