- Practice 1: discrete distribution
This module provides students an opportunity to practice applying concepts related to discrete distributions. This practice exercise asks students to calculate several values based on the data provided.
Student learning outcomes
- The student will analyze the properties of a discrete distribution.
Given:
A ballet instructor is interested in knowing what percent of each year's class will
continue on to the next, so that she can plan what classes to offer. Over the years,she has established the following probability distribution.
- Let
= the number of years a student will study ballet with the teacher.
- Let
= the probability that a student will study ballet
years.

Suppose the demand function that a firm faces shifted from
Qd 120 3P
to
Qd 90 3P
and the supply function has shifted from
QS
20 2P
to
QS
10 2P .
a) Find the effect of this change on price and quantity.
b) Which of the changes in demand and supply is higher?
