A random table is used by picking out values one at a time while closing your eyes. The 5 numbers selected are
99470
10152
09747
45400
72767

Since the values needed are percentage, we will only take the first four digits.
99.47%
10.15%
9.74%
45.40%
72.76%

The average of these values is
47.50%

Answer:

This is the best I can do. So. Yeah. I'm confused as well.

Step-by-step explanation:

A.

The favorable digits will be: 5, 6, 7, 8 and 9  

B.

Now we need all the numbers which has 5, 6, 7, 8 and 9 only.  

There are: three favorable outcomes

85585

97998  

55677

C.

Given that the problem talks about percentage our probability answer needs to be in percentage.  

3/5 = 0.6 = 60%  

There is a 60% chance for Mrs. Larsen to get a green light all five morning next week.
