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

A=No tail appears, B=No head appears.

Answer :

When two coins are tossed, total outcomes are

{HH, HT, TH, TT} =4

A=No tail occurs = {HH} =1

Probability f A = P(A) =

B= No head occurs={TT} =1

Probability of B =P(B) =

(A ∩ B) = No tail and no head occurs = not possible =0

P (A ∩ B) =

Hence, =
