Question

Ajar contains 3 white marbles, 5 orange marbles, 4 yellow marbles, and 2 black marbles. If a marble is drawn at random, find the probability that the marble is not yellow. What is the probability that the marble is not yellow? (Simplify your answer. Type an integer or a fraction.)

Answer 1

Answer:
`(2)/(7)`or 0.2857142857

Explanation:

P(not yellow)=
`(4)/(14)`

P(not yellow)=
`(2)/(7)` or 0.2857142857

Answer 2

10/14

Explanation:

See 3 +5+4+2= 14 , if the question would be what's the probability of getting yellow the answer would be 4/14 but it's not, so 14 - 4 which will be 10 so 10 / 14 .

The other way is get the sum of all the marbles except the yellow one, then that no. will be upon the total.
