Estimate the number of people in the world who are suffering from the common cold on any given day. (Answers may vary. Remember that a person suffers from a cold for about a week.)

Step 1

Let there be an assumption that on average a person catches cold thrice a year and that the population of the world is around 7.5 billion.\

Let the population of the world be denoted as *w*.

Let the number of days in an year be denoted by *n*.

Let the expected number of days a particular person has cold in a year be denoted by *m*.

*m* is calculated from the given data as,

Step 2

The probability *P *for a person to suffer from cold a given day from the information given in the problem and the assumed data,

Step 3

Here 365 is the number of days in a year,

Thus the number of people *N...*
