The probabilities of knocking down zero, one, and two pins are

and

, respectively. The total probability of knocking down at most two is thus

, or

.
26+5= 31 correct?
So lets make a chart(ish lol)

2 6
3 9
4 12
5 15
6 18
7 21
8 24
9 27
10 30
11 33
To get atleast 31 dollars you need to work 11 hours.
If you want fractions they need to work 10 1/3 hours
Hope this helped!
6 *20 = 120
8 *60 = 480
