Question

# A sample space consists of integers 1,2,3,....100. The probability of choosing an integer k is proportional to lnk. The conditional probability of choosing the integer ′2′, given that an even integer is chosen is

A
ln250ln2+ln50!
B
ln2ln2+ln50!
C
ln250ln2+ln50
D
ln2ln2+ln50

Solution

## The correct option is A ln250ln2+ln50!A= integer 2 is chosen B= Even number is chosen P(1)=λln1,P(2)=λln2,....P(n)=λln(n) P(AB)=P(A∩B)P(B)=λln2λln(2.4.6....100) =ln250ln2+ln50!Mathematics
