Answer:
Step-by-step explanation:
Given
The table
First, we calculate the amount of schools
Solving (a): Probability of 75+ computers.
From the given table, schools with 75 or more computers have the population of:
The probability is calculated as:
Solving (b): Probability of less than 75 computers.
From the given table, schools with less than 75 computers have the population of:
The probability is calculated as:
Solving (c): Probability of less than 10 computers.
From the given table, schools with less than 100 computers have the population of:
The probability is calculated as:
