Three coins are tossed simultaneously 100 times with the following frequencies of different outcomes :
Outcome: | No head | One head | Two head | Three head |
Frequency: | 14 | 38 | 36 | 12 |
If the three coins are simultaneously tossed again, compute the probability of :
(i) 2 heads coming up.
(ii) 3 heads coming up.
(iii) at least one head coming up.
(iv) getting more heads than tails.
(v) getting more tails than heads.
Given,
(i) Probability of 2 heads coming up =
= = 0.36
(ii) Probability of 3 heads coming up =
=
(iii) Probability of atleast one heads coming up =
=
(iv) Probability of getting more heads than tails =
(v) Probability of getting more tails than heads coming up =
