Agiven probability equation is p(x) = 2x-1/16 (where x can be 1,2,3 or 4) does this determine probability distribution why or why not

yes because the sum of all of the probabilities is not 1.

no because the sum of all of the probabilities is not 1.

no because the sum of all of the probabilities is 1.

yes because the sum of all of the probabilities is 1.

Yes, because the sum of all of the probabilities is 1.

Step-by-step explanation:

The given probability equation is:

, where x belongs to {1,2,3,4}.

Let us sum all the probabilities to obtain;

Since the sum of all the probabilities is 1, it is a probability distribution

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

ok then what happened.
