The probability equation for a survey on the number of speeding tickets given on a certain day in a local neighborhood is given as p(x) = 7-2x/20 (where x can be 0,1,2, or 3). does this determine a probability distribution why or why not

Solution:

The probability equation for a survey on the number of speeding tickets given on a certain day in a local neighborhood is given as p(x) = ,where x = 0,1,2, or 3.

As,  variables are discrete  ,it is the case of discrete probability distribution. And  x, takes the value, =0,1,2,3

Sum of these values must be equal to 1.

So, P(0) +P(1)+P(2)+P(3)

≠ 1

So, it is not a Probability distribution.As, sum of Probabilities of each x, value is not equal to 1.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
