Question

Q)A coin is tossed two times. find the probablity of getting at most , Atleast one head ?​

Answer 1

Heya!!

Total outcomes=4

sample space={TT,TH,HT,HH}

Favourable outcomes
(A,at most)=2{HT,TH}

P(A)=2/4

Favourable outcome
(B,at least)=3{HT,HH,TH}

P(B)=3/4

Answer 2

$\underline\mathcal{BONJOUR}$

As only 1 coin is tossed two times

Therefore,

The outcomes can be H, T, H, T

Therefore the probability of getting atmost one head can be

4/4 =1

As almost one means not more than one which we can say it can be zero also..
