Answer :
The probability that the marble is red or blue is 0.6923 or 69.23% if the bag contains five red marbles, four blue marbles, and four yellow marbles. You randomly pick a marble.
What is probability?
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
We have the total number of marbles = 5+4+4 =13
Total number of red and blue marble = 5+4 = 9
The probability that the marble is red or blue = 9/13 = 0.6923 or
= 69.23%
Thus, the probability that the marble is red or blue is 0.6923 or 69.23% if the bag contains five red marbles, four blue marbles, and four yellow marbles. You randomly pick a marble.
