What is the probability of fatherhood in this scenario?
Say 3 equally fertile men have sex with 1 woman all at once. She becomes pregnant from this specific incident.
Is each man's probability of being the dad 1:2 or is it 1:3? Or another figure entirely?
Please explain.
| 1:2 | 0 | |
| 1:3 | 7 | |
