I got the following question on a practice test, and cannot figure it out. The correct answer, according to PR, is A. I thought initially it was D. If someone can explain to me the rationale, most importantly why B is not sufficient, I would greatly appreciate it.
" A bowl is filled with consecutively numbered tiles from 1 to x. Joe pulls out a tile
and uses it to contruct sequence Q, which consists of 10 consecutive integers starting
with the number drawn. If Joe then selects one number from Sequence Q, what is the
probability that the selected number is a multiple of 3?
1.) The last number in sequence Q is a prime number that is less than 20.
2.) x (is less than or equal to) 10
"
Thanks.
