Question

a coin is tossed thrice what is the probability of getting a head in the second toss and a tail in the third

Answer 1

Hey friend nice question
coin is tossed thrice
S =(HHH, HHT, HTH,HTT, THH, THT, TTH! TTT) n(S) =8
A=(HHT,THT)
n(A)=2
P(A)=n(A)/n(S)
= 2/8 =1/4
Therefore, p(A) =1/4
Hope this helps you.
