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) =
