Answer :
Answer:
50% of the time
by adding the number of times he does a 10-hour shift and the number of times he does a 12-hour shift, we get 1/2 which is equal to 50%
Step-by-step explanation:
the shifts that are greater than 8 are the 10 and 12 hours shifts
he does the 10 hour shift 1/3 of the time and the 12 hour shift 1/6 of the time
add both fractions
[tex]\frac{1}{3}[/tex] + [tex]\frac{1}{6}[/tex]
[tex]\frac{2+1}{6}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
to convert to percentage, multiply 1/2 by 100
1/2 x 100 = 50%
