Required probability = 120 * 0.0010819 =  0.1298

Answer:
 $57.60
Step-by-step explanation:
Marcus lays a slab of concrete in 3 hours. Tony lays the same size slab in 2 hours. The number of hours used by both men will be:
1/3x + 1/2x = 1
2x + 3x = 6
5x = 6
x = 6/5 = 1.2 hours.
The cost of labor will be:
= 1.2 hours × $48
= $57.60
