Compute Theoretical Probability
-A bag contains 7 red marbles, 2 blue marbles, and 1 green marble. What is the probability of choosing a marble that is not blue when one marble is drawn from the bag?
A) $\frac { 4 } { 5 }$
B) $\frac { 5 } { 4 }$
C) $\frac { 1 } { 5 }$
D) 8

The total number of marbles is 10 (7 red + 2 blue + 1 green). The probability of not choosing a blue marble is the number of marbles that are not blue (which is 8) divided by the total number of marbles, giving $\frac{8}{10}$ which simplifies to $\frac{4}{5}$.
