Answer:
a) Discrete random variable
b) Continous random variable.
Step-by-step explanation:
a) As the number of people can take only integer values, from 0 to n (0, 1, 15, 256, for example, but not 5.6) and not decimals values, we can say that it is a discrete variable.
b) In this case, the weight of a Upper T dash bone steak is a physical variable and can take decimals positive values (0.645 lbs for example).
Then, this variable is a continous variable.
