Step-by-step explanation:
Probability event = number of times the event occurs divided by the number of trials occur.
When you apply this then you find the experimental probability as it means the amount of probability that is based on repeated trials.
So as shown we number of events/ number of trials. f the colour is blue x 2 then 2/7 is the answer.
Frequency means the amount of times the event occured.
Relative frequency means estimating the amount after finding the probability.
