Because the probability is uniform (equally likely) between 20 and 100 pounds, the probability distribution is uniform between 80 and 100 pounds, with the value 1/(100-20) = 1/80 chocolates/pound.

Let x =  random variable that represents pounds of chocolate consumed.
Therefore
P(x < 60) = (60 - 20)*(1/80) = 1/2.

Answer: The probability is 1/2.

Explain, using an example, why need to multiply when converting from a larger unit to a smaller unit?
sveta [45]

Answer: Because you need more of a smaller unit to equal a larger unit.

Example:

If you want to convert 5km to meters, there must be more meters than kilometers.

5km(\frac{1000m}{1km} )=5000m
