Two coins are tossed once. Find P(A/B) in each of the following:

A=Tail appears on one coin, B= One coin shows head.

Answer :

When two coins are tossed, total outcomes are


{HH, HT, TH, TT} =4


A=Tail appears on one coin= {HT, TH} =2


Probability of A = P(A) =


B= One coin shows head ={HT, TH} =2


Probability of B =P(B) =


(A B) = one coin shows head and another shows tail = {HT, TH} =2


P (A B) =


Hence, =


= (answer)
