Question 1112389
Do 0, 1, 2 successes and subtract the combined sum from 1
For 0, it is .5^6=0.0156
For 1 it is 6C1(1/2)^6, which is 6 times the first or 0.0938
For 2 it is 6C2(1/2)^6, which is 15 times the first or 0.2344
The sum of those 3 is 0.3438

The probability is for at least 3 successes, so that is 1-0.3438 or 0.6562
