Answer;

Given by;

It’s "true",

The number of people suffering complications after surgery in a given week is a discrete random variable as consider by:

Because:

The number of people can be only take values given as like 0,1 ,2 ,50 etc…

Therefore,

Its discrete variable.

    4. At a local hospital, babies are born at an average rate of four births per night (consider "night" to be an 8 hour period from 10pm to 6am). Assume that the time that elapsed from one birth to the next has the exponential distribution. Take note that we are concerned only with the rate at which babies are born, and we are ignoring the time spent in labor. We must also assume that the times spent between births are...
