The probability for event A is 0.3, the probability for event B is 0.6, and the probability of events A or B is 0.8. Why are the events not mutually exclusive? The sum of P(A) and P(B) is less than P(A or B).
The product of P(A) and P(B) is less than P(A or B).
The product of P(A) and P(B) is not equal to P(A or B).
The sum of P(A) and P(B) is not equal to P(A or B).

step-by-step explanation:

it would be:

c.parallelogram.

im not sure

step-by-step explanation:

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
