Question

a balance coin is tossed three times ,then find the probability of (H,H,T)​

Answer 1

Step-by-step explanation:

sample space={(HHH)(TTT)(HTH)(THH)(HHT)(HTT)(THT)(TTH)}

n(S)=8

A={(HTH)(THH)(HHT)}

p(A)=n(A)/n(S)

=8/3

Answer 2

Answer:

(T,T,T),(T,T,H),(T,H,H),(H,H,H),(H,H,T),(H,T,T),(T,H,T),(H,T,H)

Ans.=1/8

《or》

(H,H,T),(T,H,H),(H,T,H)

P(E)=no.of favorable outcomes/total no.of outcomes

3/8
