Alarge bag of marbles contains an equal amount of red, orange, yellow, blue, and green marbles. quinn randomly selects 1 marble from the bag. which of the following represents the probability of selecting a red or blue marble?

40% because if their are 5 colors of equal amounts, than each one is 20% amd if you try and get 2 then you multiply %20 by 2 and you get %40

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
