On a multiple choice test, if you randomly guessed on three questions, then what is the probability you got at least one of them correct?

Number of Questions =3

Probability of giving a correct answer

Probability of giving two correct answers

Probability of giving all correct answers

Probability that at least one of them is correct

Probability that two of them is correct

Probability that all of them is correct

So, Required probability

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
