Question

It's the (IV) question with the spinning sector really need this answer anything will be appreciated it's got to do with probability

Answer 1

Add up the frequencies to find the total frequency and that is your denominator.
5+10+12+10+13=50
Then their frequencies are the numerators.
5/50
10/50
12/50
10/50
13/50
Then times the fractions by two to make the denominator 100 so that you can easily turn these fractions into percentages.
10/100 = 10%
20/100 = 20%
24/100 = 24%
20/100 = 20%
26/100 = 26%
Then just double check that they add up to 100%
