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

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

roots are from trees

step-by-step explanation:

1 ?

step-by-step explanation:

u said 1+1+1+1+1+1+1+1+1+1+1+1*0 so ur adding 1 but then multiplying by 0 so its 0 but then u said 1*0+1 so now ur adding 1 so the answer is juan ?
