You have a bag with 6 green marbles, 15 blue marbles, 8 red marbles, 1 yellow marble. What is the probability (as a decimal rounded to three places) of pulling
out a red marble?

0.267 or 26.7%

Step-by-step explanation:

The probability of an event happening is calculated by dividing the favorable outcomes by all outcomes:

The sum of all events (marbles) is 6 + 15 + 8 + 1 = 30

The number of favorable events is 8

Therefore, the probability is 8/30 ≈ 0.267 or 26.7%

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
