Determine whether the situation calls for a discrete or continuous random variable.
The number of freshmen in the required course, English 101
The braking time of a car
I think the first one discrete and the second is continous is this correct?
you are correct.
4/3x+2/3x
Yes, you are correct!
1. The number of freshmen in the required course, English 101, would typically be considered a discrete random variable. This is because the number of freshmen is usually quantized or counted in whole numbers. You can't have a fraction or a non-integer number of freshmen.
2. The braking time of a car would typically be considered a continuous random variable. This is because the braking time can take any non-negative value within a certain range. It could be measured in fractions of a second and can vary continuously, rather than being restricted to specific whole number values.
