Total no of outcomes= 2^2=4
No of outcomes, that give atleast one head=3(hh, ht, th)
Probability of an event= No of favourable outcomes/total no of outcomes
=> 3/4= 0.75......

Given,
A coin is tossed two times then the probability for atleast one head is:
The chances are [ HH, TH, HT, TT ]
Total outcomes = 4
Favourable outcomes = [ HH, HT, TH ] = 3
Probability = Favourable Outcomes / Total Outcomes.
= 3/4
Therefore, If a coin is tossed two times then the probability of getting at one head is 3/4.
