Two coins are tossed 1000 times and the outcomes are recorded as given below:
Number of heads | 0 | 1 | 2 |
Frequency | 240 | 450 | 310 |
In a simple throw of two coins, what is the probability of getting
(i) at most one head? (ii) At least one head?
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) =
