Given:
Results of a spinner shown in the table.
To find:
The experimental probability of the spinner landing on a 1 or 7.
Solution:
From the given table it is clear that,
Spinner landing on 1 = 12 times
Spinner landing on 7 = 9 times
Spinner landing on 1 or 7 = 12+9 = 21 times
Total number of times spinner landed = 12+35+72+29+40+18+9+65+42 = 322 times
Now, the experimental probability of the spinner landing on a 1 or 7 is
Therefore, the correct option is A.
