1/2*1/2*1/2*1/2

Answer 4

first u should get a head probability is 1/2 again u want a head probability is 1/2
then tail and tail again so probality is 1/2 and 1/2 again

just multiply all probabilities because all the tosses are independent of each other

Answer 5

Is there any other way of solving it?
