simple probability question
3 events, they odds of them happening are, 1/3 1/3 2/5
what are the odds that 2/3 of those events will occur, it can be any 2 out of those 3. thanks. |
Re: simple probability question
As long as they are not related:
First 2: 1/3*1/3*3/5= 3/45 First and Last: 1/3*2/3*2/5 = 4/45 Last 2: 2/3*1/3*2/5= 4/45 So 11/45 that exactly 2/3 will occur. If you include the case when all 3 occurs, 1/3*1/3*2/5= 2/45, total probability is 13/45. |
