In a simple throw of two coins, what is the probability of getting

(i) at most one head? (ii) At least one head?

Answer :

Total number times a coin is tossed = 1000


Number of times no heads occurred = 240


Number of times one head occurred = 450


Number of times two head occurred = 310


Probability P() =


(i) Probability of getting at most one head is (that is Probability of no head and one head)


P( at most one head) =


(ii) Probability of getting at least one head is (that is Probability of one head and two head)


P( at least one head) =
