The probability that a blue marble is drawn out of a bag is 3/5.

what is the probability that a blue marble is not drawn?

a) 1/5

b) 2/5

c) 3/5

d) 4/5

Logical equivalent of the give question is its contrapositive

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!
