Answer:

b) 10

Step-by-step explanation:

In this case the frequency would be equal to the quotient between the sample that creative artists tell us (that is to say 120 people) and the amount of sastrological signs that there are (that is to say 12 signs), therefore it would be:

F = 120/12 = 10

Which means that the expected frequency for each category equal to 10.

So the answer is b) 10
