Final answer:
The ratio of members who don't have cable to the total number of members is calculated by dividing the number of members who don't have cable by the total number of members.
Step-by-step explanation:
The ratio of members who don't have cable to the total number of members can be calculated by dividing the number of members who don't have cable by the total number of members. In this case, the total number of members is 3250. According to the information provided, the organization's membership list includes both members who have cable TV and members who don't have cable. So, to find the number of members who don't have cable, subtract the number of members who have cable from the total number of members. Let's assume the number of members who have cable is x, then the formula for finding the number of members who don't have cable would be: Total number of members - x = Number of members who don't have cable.
The ratio is the number of members who don't have cable divided by the total number of members. So, the ratio can be calculated as: Number of members who don't have cable / Total number of members.
Let's assume the number of members who don't have cable is y, then the formula for calculating the ratio would be: y / 3250.
