Question

A marble is drawn at random from the bag shown below. The bag contains 3 green, 4 yellow, 5 blue, and 8 pink marbles.What is P(not pink)?

Answer 1

Chance of drawing each color: 

green= 3/20
yellow= 4/20
blue = 5/20
pink = 8/20

Without additional information you cant solve this question

Answer 2

Answer: $\dfrac{3}{5}$

Step-by-step explanation:

Given : The number of pink marbles in bag= 8

Total number of marbles in bag= $4+5+8+3=20$

Now, the number of marbles that are not pink =$20-8=12$

We know that the formula to find the probability is :-

$\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}$

Similarly, $\text{P(not pink)}=\dfrac{12}{20}=\dfrac{3}{5}$
