Question

A jar contains 18 marbles that are the same size. It contains 7 purple, 3 green, and 8 orange marble. What is the probability of not picking an orange marble? Type your probability as a fraction in simplest form.​

Answer 1

5/9

Explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

probability of not picking orange = total marbles that are not orange / total number of marbles

total marbles that are not orange = 7 +3 = 10

10 / 18

To transform to the simplest form. divide both the numerator and the denominator by 2

= 5/9
