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 =
