Answer 9

We wish to find which of the five marbles could be blue (be careful about "which of the following statements MUST be true" followed by "possibilities," it only asks for all possible values).

We know that marble 1 cannot be red. Marble 2 may or may not be blue. Marble 3 is obviously blue. Marble 4 cannot be blue because marble 1 is red. Marble 5 is the same color as marble 2, which could be blue. Here, we note that marble 3 is blue and marbles 2 and 5 are either both blue or both a different, non-blue color. Hence, the only possible values of x are 1 and 3.

Answer 40

A jar contained 10 marbles-some red,some white, and some blue. The information above is about 5 marbles that were drawn from the jar.

Answer 41

Don't worry about why there are a total of 10 marbles . That does not affect the answer . He might well have put 15 marbles - the answer would still be the same.
