"determine whether or not the distribution is a discrete probability distribution and select the reason why or why not.

p(x=x) 1/2 5/8 3/4
answer first, decide whether the distribution is a discrete probability distribution, then select the reason for making this decision. decide reason"
(yes / no)
(a) since the probabilities lie inclusively between 0 and 1 and the sum of the probabilities is equal to 1. (b) since at least one of the probability values is greater than 1 or less than 0. (c) since the sum of the probabilities is not equal to 1. (d) since the sum of the probabilities is equal to 1. (e) since the probabilities tie inclusively between 0 and 1.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
