If the probability of THREE qt3.14s being my gf is 50% for each qt3.14, what is the probability that atleast ONE qt3.14 will be my gf?

Assume that the three qt3.14s are independent (mutually exclusive).

>>	Anonymous Sun Dec 4 08:49:16 2016 No.8514640 >>8514632 means their decisions will be independent. So they will have no prior contact to discuss whether they would want to be a gf to some weeb autist

>>	Anonymous Sun Dec 4 08:50:13 2016 No.8514643 I knew weebs were all in high school. The probability that none of the will be your gf is 1/2 * 1/2 * 1/2 = 1/8, so the probability that at least one will be your gf is 1 - (none will be your gf) = 1 - (1/2 * 1/2 * 1/2) = 1 - (1/8) = 7/8

>>	Anonymous Sun Dec 4 08:53:00 2016 No.8514650 >>8514643 >the probability that at least one will be your gf is 7/8 that seems a bit impossibly high

>>	Anonymous Sun Dec 4 08:58:31 2016 No.8514655 >>8514650 but it's the answer, you can solve it the old fashioned way if you want. prob(1gf) = 3! /(2! 1!) ( 1/2 * (1/2)^2) prob(2gf) = 3! /(1! 2!) ( (1/2)^2 * (1/2)) prob(3gf) = 1/2 * 1/2 * 1/2 so in total it's 3/8 + 3/8 + 1/8 = 7/8

I agree, seems extremely unlikely that atleast one girl would be your gf if the probability was 50% for each. In reality, the probability would most likely be 0, but this theoretical calculation is describing fantasy even if the girls were 3DPD

>>8514682
how wold the "real" probability be close to 0 if each even has 50% chance of happening ? It's the same as flipping a coin, you flip a fair coin 3 times what's the prob that you get at least one tail ? Would you still argue it's close to 0 because 50% per event is too low ?

>>	Anonymous Sun Dec 4 09:24:30 2016 No.8514701 >>8514694 Real life outcomes are binary. It will happen or won't happen. Considering subjective qualities that the girls find out that OP is an autistic pervert the probability that one of them will still be their gf is either 1 or 0 so 50%

>>	Anonymous Sun Dec 4 10:47:54 2016 No.8514809 >>8514690 >>8514630 It's 100% minus the probability that none of them will be your gf, which is (1/2)^3. So yes, 87.5% is correct.
