Answer:
5/8
Step-by-step explanation:
The sectors are labeled 1,2,3,4,5,6,7,8
Numbers less than 4: 1,2,3
Multiples of 4: 4,8
We are looking for 1,2,3,4,8 = 5 choices
P (1,2,3,4,8) = Number of choices/ total
= 5/8
500 is the answer
1/3,0,9
9,3,27
1/9,3,27
70 degrees.
Add up all the values and divide by 5.
350/5 = 70.
