One ticket is selected at random from 100 tickets numbered 00,01,02,...,98,99. If `x_1, a n dx_2` denotes the sum and product of the digits on the tic
Correct Answer - A Let the number selected be xy. Then `x+y=9,0lex,yle9` `and xy=0impliesx=0,y=9or y=0,x=9` `P(x_(1)=9//x_(2)=0)(P(x_(1)=9nnx_(2)=0))/(P(x_(2)=0))` Now, `P(x_(2)=0)=19/100` `andP(x_(1)=9nnx_(2)=0)2/100` `impliesP(x_(1)=9//x_(2)=0)=(2//100)/(19//100)=2/19`

One ticket is selected at random from 100 tickets numbered `00,01,02, …, 99.` Suppose A and B are the sum and product of the digit found on the ticket
Correct Answer - B The sum of the digits can be 7 in the following ways: `07,16,25,34,43,52,61,70.` `therefore(A=7)={07,16,25,34,43,52,61,70}` Similarly, `(B=0)={00,01,02...,10,20,30,...,90}` Thus, `(A=7)nn(B=0)={09,70}` `thereforeP((A=7)nn(B=0))=2/100,P((B=0))=19/100` `P(A=7)|B=0=(P((A=7)nn(B=0)))/(P(B=0))` `=(2/100)/(19/100)=2/19`

The box contains tickets numbered from 1 to 20. Three tickets are drawn from the box with replacement. The probability that the largest number on the
Correct Answer - D Let X denote the largest number on the 3 sticks drawn. Then, `P(Xle7)=(7//20)^(3)and P(Xle6)=(6//20)^(3).` Then, the required probability is `P(X=7)=((7)/(20))^(3)-((6)/(20))^(3)`
