a coin is tossed 8 times . what is the probability of getting exactly 7 heads ?
"the number of possible outcomes is 2 ^ 8 = 256 there are 8 ways to get exactly 7 heads . p ( exactly 7 heads ) = 8 / 256 = 1 / 32 the answer is c ."
multiply(power(divide(const_1, const_2), 7), multiply(choose(8, 7), divide(const_1, const_2)))
