If you flip 10 pennies all at the same time what is the probability that exactly 3 will come up heads and 7 will come up tails?
Almost 12 % It's the same as flip a penny ten times. There are 2^10 = 1024 different outcomes (each penny being either head or tail). The ones we can 'use' are those with 3 heads. Let '1' be head and '0' be tail: 0001010100 is a valid outcome - and 1110000000 as well. So how many way can we arrange three 1's in ten spaces? In 120 ways. 120 ways out of 1024 is the answer. 120/1024=0.1171875 = 11.71875 %
