Aprofessor rolls a fair, six-sided die. using the classical method of probability, what is the probability that at least three spots will be showing up on the die

The required probability is 2/3.

Step-by-step explanation:

It is given that a professor rolls a fair, six-sided die.

We need to find the probability that at least three spots will be showing up on the die.

Total possible outcomes = {1,2,3,4,5,6}

Number of total outcomes = 6

At least three spots will be showing up on the die.

Favorable outcomes = {3,4,5,6}

Number of favorable outcomes = 4

Formula for probability:

Therefore, the required probability is 2/3.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
