Question 1004897: The spinners are spun and the results are added. Find P(sum is 8).
Spinner #1.) 3/4 is 4. 1/4 is 2
Spinner #2.) 1/3 is 2. 1/3 is 4. 1/3 is 6. Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! To get a sum of eight, we would need a 4 and a 4 or a 2 and a 6...we add the probabilities for each...
For a 4 and a 4, we multiply 3/4 and 1/3 to get 1/4.
For a 2 and a 6, we multiply 1/4 and 1/3 to get 1/12.
Now add 1/4 + 1/12 = 4/12 = 1/3
