probablity--1982

This is not a very difficult question.. Try by venn diagram...

first \\P(A^c|B^c)=\frac{1-P(AUB)}{1-P(B)}=\frac{1-P(A)-P(B)+P(A\bigcap{B})}{1-P(B)}=\\\frac{1-P(A)-P(B)+P(A)P(B)}{1-P(B)}=1-P(A)

The first result is an outcome of venn diagram

wat is the meaning of P(A/B) i mean the division sign???

yup eureka.. that is an answer \

BUt depends on t;he 4 choices that you have..

shubhomoy, ;you dont need to wait that long.

it simply means that the probability of A complement given that B has not occured (B complement has occured)

ok!! ab samajh me aaya!
