Acoin is tossed two times. the set of outcomes is given as s = {hh, ht, th, tt}. let x represent the number of times heads occurs.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

step-by-step explanation:

if x = 2 you have to find x to finish the problem
