Answer:
Step-by-step explanation:
The ration of weight of nickel, zinc, and copper in an alloy is 4:1:2
The weight of alloy can be written as
4x + x + 2x = 35 Kg
7 x = 35 Kg
X = 35 Kg/7
X = 5kg
The weight of nickel the alloy = 4 x 5 = 20 Kg
The weight of zinc in the alloy= 1 x 5 = 5kg
The weight of copper in the alloy = 2 x 5 = 10 kg
There can only be integer number of passengers. We cannot have 1.372 passengers in a car, so that would be discrete random variable.
