### Instruction: There is a total of 84 marbles in a box, each of which is red, green, blue, or white. If one marble is drawn from the box at random, the probability that it will be white is 1/4 and the probability that it will be green is 1/7. What is the probability that the marble will be either red or blue?
Answer Choices: (A) 4/7 (B) 9/14 (C) 11/14 (D) 17/28 (E) 23/28 Let's program in Python in the response.### Response: # The total probability should be 1. So the probability of the marble being either red or blue is 1 - (probability of white + probability of green)
prob_white = 1/4
prob_green = 1/7
prob_red_blue = 1 - (prob_white + prob_green)
print(prob_red_blue)
