Answer:
B. Black
Explanation:
On the spinner, there are 10 sections.
The theoretical probability of getting a certain colour is as follows.
Black = 2 sections / 10 sections = 1/ 5
Blue = 4 sections / 10 sections
Red = 3 sections / 10 sections
Green = 1 section / 10 sections
Now the experimental probability is the actual probability of getting a certain colour when the spinner was spun.
There were a total of 40 spins and the probabilities of getting a certain color is given by the table. From the table, we extrapolate the experimental probability as follows
Black = 8 / 40 = 1/ 5
Blue = 12 / 40 = 3/ 10
Green = 10 / 40 = 1/ 4
Red = 10 / 40 = 1/4
From the above, we see that the experimental probability of Black is equal to the theoretical probability.
Hence, choice B is correct.
