Probability outcome and frequency question

Question

The table shows the results of spinning a spinner several times.


Outcome A B C D E
Frequency 2 4 3 1 2



What is the experimental probability of spinning a C or a D?



A. 4/5




B. 1/48




C. 1/3




D. 2/5

Answer 1

The probability of spinning a C or a D = number of times C and D were spun /total number of spins experimentally.

so p(C or D) =4/12=1/3
