Question

A bag contains 7 marbles of which 1 is orange. What is the probability that a randomly selected marble will NOT be orange?

a) 1/7
b) 6/7
c) 1/6
d) 5/7

Answer 1

The probability that a randomly selected marble will NOT be orange is 6/7.

Step-by-step explanation:

To find the probability that a randomly selected marble will NOT be orange, we need to calculate the number of marbles that are not orange and divide it by the total number of marbles in the bag.

There are 7 marbles in total, and only 1 of them is orange. So, the number of marbles that are not orange is 7 - 1 = 6.

Therefore, the probability that a randomly selected marble will NOT be orange is 6/7.
