Question

two coins are tossed simultaneously . write the sample space s and number of sample points n (s)
plz tell me the answer​

Answer 1

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

Answer 2

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 $\frac{1}{2}$.
• 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 ;  $\frac{3}{4}$ .
