A spinner has four sections lettered A, B, C, and D. The table shows the results of several spins. Find the experimental probability of spinning each letter as a fraction in simplest form, a decimal, and a percent.

experimental probability is the outcome during a certain experiment. add up the total number of times it was spinned. You should get 40. To find the experimental probability of each section, simply divide the number by 40. This will give you the percentage for each one. For example, spinner A. 14/40=.35  Multiply this by one hundred to find the percentage (35%). Do this for all and let me know if you need help converting them to fractions. :)

Answer: Probability of getting A is given by
(7)/(20)=0.35=35%

Probability of getting B is given by
(7)/(40)=0.175=17.5%

Probability of getting C is given by
(11)/(40)=0.275=27.5%

Probability of getting D is given by
(8)/(40)=(1)/(5)=0.2=20%

Explanation:

Since we have given that

Number of possible outcomes of getting A = 14

Number of possible outcomes of getting B = 7

Number of possible outcomes of getting C = 11

Number of possible outcomes of getting D = 8

Total number of possible outcomes would be

14+7+11+8

=40

So, Probability of getting A is given by
(14)/(40)=(7)/(20)=0.35=35%

Probability of getting B is given by
(7)/(40)=0.175=17.5%

Probability of getting C is given by
(11)/(40)=0.275=27.5%

Probability of getting D is given by
(8)/(40)=(1)/(5)=0.5=20%
