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: the answer to your question is parallel

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
