Average Sports Participation

A local sports club conducted a survey among its members to find out how many times they played sports in a week. The results of the survey are shown below:

• 1 time: 5 members
• 2 times: 10 members
• 3 times: 15 members
• 4 times: 20 members
• 5 times: 10 members

To find the average number of times the members played sports in a week, you need to calculate the mean from these results. What is the average number of times played?
