Ordinary (fair) die Is a cube with the 1 numbers 1 through 6 on the sides (represented by palnted spots). Imagine that such a die Is rolled twice In succession and that the face values of the two rolls are added together. This sum Is recorded as the outcome of a single trial of a random experiment.
of compute the probability of each of the following events.
Event A: The sum Is greater than 6.
Event B: The sum Is an even number.

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
