Answer:
V = 108,000,000pi or V = 339292007mm
Step-by-step explanation:
V = pi × r^2 × h
To find radius with circumference:
Radius = Circumference / 2pi
So, 1884/2pi = 299.847913 = 300
V = pi × 300^2 × 1200
V = pi × 90000 × 1200
V = pi × 108000000
V = 108,000,000pi or V = 339292007
We want to find the probability that Berenice gets all the answers correct.
<u>1 question:</u>
Each question has 4 options, each option has the same probability of being the correct option, so she has a 25% of<u> randomly selecting the correct option.</u>
Then the probability here will just be equal to the number of correct options (1) over the total number of options (4)
p = 1/4
2 questions:
We already know the probability for one question, then the probability of getting two questions correct will be equal to the <u>product of the individual probabilities</u> for each question:
p = (1/4)*(1/4 = 1/16
3 questions:
Similar approach as before:
p = (1/4)*(1/4)*(1/4) = 1/64
4 questions:
p = (1/4)*(1/4)*(1/4)*(1/4) = 1/256
