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

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%
