You and your friend are among 5 volunteers to help distribute workbooks. What is the probability that your teacher randomly selects you and your friend to distribute the workbooks?

1/10 or 10%

Step-by-step explanation:

Volunteer one, two, three, four and five

There are many pairings, they are;

One + two,

One + three,

One + four,

One + five,

Two + three,

Two + four,

Two + five,

Three + four,

Three + five,

Four + five.

This means there are 10 possible pairings.

This shows that the chances both you and your friend will be chosen is 1/10

Hope that helped :)

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
