Asporting goods store received an order of 80 baseball caps, of which 12 were green. if 1 of the 80 caps is selected at random, what is the probability it will not be green?

Step-by-step explanation:

Given: The total number of caps = 80

The number of green caps = 12

Then , the number of caps which are not green =

If 1 of the 80 caps is selected at random, what is the probability it will NOT be green is given by :-

Hence, the probability it will NOT be green

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
