Sample space S={(H,H),(H,T),(T,H),(T,T)}
Number of sample space n(S)=4
D= getting no head
D={(T,T)}
n(D)=1

Given Data: 2 coins.
To Find: Sample space S and number of sample points.
Solution:
- Probability is defined as the outcome for an event.
- For example, In a coin there is Head and a Tail. Probability of getting an head is 1. There are two outcomes so getting an head is
.
- Sample space is the collection of outcomes.
- Similarly for 2 coins the Possibilities are {HH} - 2 Heads, {HT} - One Head and a Tail, {TH} - One tail and a Head, {TT} - Two tails.
- The Sample space S = {HH, HT, TH, TT}. n(s) = 4.
- Probability of getting at least is {HH, HT, TH} = 3 ;
