Answer: a) 
Step-by-step explanation:
Since we have given that
Number of red marbles = 3
Number of yellow marbles = 4
Number of green marbles = 6
Total number of marbles = 3 +4 +6 = 13
a) the marble is red?
Probability of getting a red marble = 
b) the marble is not yellow?
Probability of not getting yellow = 
c) the marble is either red or green?
Probability of getting either red or green = P(red) + P(green) =
d) the marble is neither red nor green?
Probability of getting neither red nor green = P(getting yellow) = 
Hence, a)
In your question where as the amount of gasoline that 80 drivers bought to fill their cars gas tanks is shown in your diagram and the problem as to find how many drivers bought more than 12 gallons and the best answer would be 36. I hope you are satistfied with my answer and if you need some clarification, please feel free to ask for more

Draw a straight line. Label the left side "0" and then make lines with
"2" "3" and "4".
1/3 means it i 1/3rd of 1. Which means you need to divide everything from 0 - 1 into 2 segments. The first segment on the left side is your 1/3rd spot. The next one is your 2/3rd place, and then finally the 1 is your 3/3 (or one whole.)
