Two coins are tossed simultaneously 80 times and the outcomes were recorded as under:


Outcome



Two heads



One head



No head



Frequency



24



36



20



If two coins are tossed at random,find the probability of getting


(i) Two heads (ii) one head (iii) no head

Total number times a coin is tossed = 80


Number of times two heads occurred = 24


Number of times one head occurred = 36


Number of times no head occurred = 20


Probability P() =


(i) Probability of getting two heads is


P(Two heads) =


(ii) Probability of getting one head is


P(one heads) =


(iii) Probability of getting no head is


P(no head) =
