Need !   what is theoretical probability and experimental probability?

Theoretical probability is what is expected to happen without conducting an experiment. In other words, it's a method to express what what is expected to happen based on the number of favorable outcomes and the number of total outcomes. For example, in the image provided, I attached a spinner.

The probability of spinning a 4 is 1/4 because there is 1 favorable outcome which is spinning a 4 and there are 4 possible outcomes which is spinning a 1, 2, 3, or 4. It's important to understand that each outcome is equally likely. This means in theory, there is a 1 in 4 chance we will spin a 4.

We can also find probability of given event by conducting an experiment. Experimental probability is when you actually conduct the experiment. In the second image provided, these could be possible results if you actually spun the spinner.

idk this answer sorry cant on this one.

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
