What type of probability distribution can be used to find out the probability that there will be no customers arriving at a checkout counter in 10 minutes?

Step-by-step explanation:

What is  Poisson distribution?

A Poisson distribution is a statistical analysis that describes the number of times that an event will likely occur during a period of time.

The expression for the distribution is given as

P(x; μ) = (e-μ) (μx) /x!

Where x is the actual number of successes that result from the experiment, and e is approximately equal to 2.71828.

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
