In: 3

Answer 1

Let’s ignore the airliner crashes and simplify by going to coins (1 in 2).

If two people use the same coin, they both have a 1/2 chance of H. If they use two coins, 1/4 both H, 1/4 both T, and 1/2 one H, one T.

Each person still have the same probability of H in all cases. The probability of *both* getting H is smaller.

Your question isn’t clear so there’s not really a good way to answer.
