Answer 1

Answer:

The answer is 3/4

Step-by-step explanation

• possible outcome divided by total outcomes
• add other three coulr balls and divide by the the total number of balls.
• 12/16= 3/4

Answer 2

Step-by-step explanation:

Answer is 3/4

because We have to fins out that ball drawn in not white

n = 16

Here P(A) is white ball and P(A') is non white ball

P(A) = 4/16

Therefore P(A') = 12/16

Thus P(A') =3/4
