Answer 1

The number of times the spinner will land on an odd number in 200 trials is 80 times

How to determine the number of times?

The sections on the spinner are given as

Sections = 1 to 7

From these sections, we have

Odd sections = 1, 3, 5 and 7

From the dot plot given, the total frequency of the odd sections is

Frequency of odd sections = 3 + 1 + 2 + 2

Evaluate

Frequency of odd sections = 8

Also, we have

Total frequency = 20

The number of times is then calculated as

Number of times = Frequency of odd sections/Total frequency * 200

So, we have

Number of times = 8/20 * 200

Evaluate

Number of times = 80

Hence, the number of times is 80 times
