Before Brian starts messing with them, there are 24 balls in the bag.
9 of them are white.

-- The probability that Brian draws a white ball from the bag is  (9/24) .

If he has already drawn one white ball and put it aside, then there are
23 balls left in the bag, and 8 of them are white.

-- The probability that Brian draws a white ball from the bag this time
is  (8/23) .

So the probability of white balls on both draws is

     (9/24) x (8/23)  = 

              (72/552)  = 

                 3 / 23  =  about <em>13%  </em>(rounded)

Hello! Could y’all please explain why this is Decay and not growth?
svetlana [45]

Answer:

This is an Exponential Decay

Step-by-step explanation:

A = 1200(0.85)⁶

The above expression is an Exponential Decay because 0.85 is less than 1

The formula for Exponential Decay

= y = a (1 - r)^t

We equate both equation together

Where

a = 1200

1 - r = 0.85

t = 6

Solving for r

1 - r = 0.85

r = 1 - 0.85

r = 0.15

Converting to Percentage

r = 15% decay rate
