Question

4,5,6,7,8,9,10,X
if a number is chosen from the list above the probability that a mulitple of 3 will be chosen is 1/4 which of the follwoing could be value of x
A.15
B.24
C.99
D.101

Answer 1

that would be 101....because the X cannot be a multiple of 3 in order for the probability to be 1/4.

so if we had... 4,5,6,7,8,9,10,101
total of numbers that are multiples of 3 = 2
total of all numbers = 8

and 2/8 = 1/4

Answer 2
