Determine whether the distribution is a discrete probability distribution.

x p(x)

0 0.13

1 0.27

2 0.18

3 0.27

4 0.13

is the probabily distribution a discrete distibution? why?

a- yes, because the distribution is symmetric.

b- yes, because the probabilities sum to 1 and are all between 0 and 1, inclusive.

c- no, beacause some of the probabilities have values greater than 1 or less than 0.

d- no, because the total probability is not equal to 1
