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

D- No, because the total probability is not equal to 1.

Step-by-step explanation:

If X is a random variable with a discrete probability distribution, then

1. 0≤P(x)≤1 , for any value of x.

2. The sum of the probabilities must be equal to 1.

The given discrete probability distribution :

X   P(x)  

0   0.13

1   0.27

2   0.18  

3   0.27

4   0.13

Here , each probability is greater than 0 and less than 1 , so first condition is satisfied.

The sum of probabilities = 00.13+0.27+0.18+0.27+0.13=0.98≠ 1  

It means , the second condition is not satisfied.

Thus , the probability distribution is a discrete distribution.

Hence, the  correct answer is : D- No, because the total probability is not equal to 1.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

only 10/60 isn't equivalent

hope this : )
