Left-Handed Golfers Probability Question

that sounds like math to me...

but it brings to mind the old joke about the guy talking to his wife about death. and she says that if she passes first, she wants him to remarry. but she doesn't want him to let his next wife use her golf clubs, as they are special to her.

and his reply is not to worry about it as his girlfriend is left handed...

The probability that at least one of a twosome is left-handed is one minus the probability that both are right-handed:
1 - 0.9^2 = 1 - 0.81 = 0.19

The probability that both twosomes have at least one left-handed golfer is the square of the above probability:
0.19^2 = 0.0361

The odds are 9639 to 361 (approximately 26.7 to 1) against.
