Answer:
40 days
Step-by-step explanation:
20 men = 30 boys can do the job so
10 men = 15 boys
30 boy hours = 36 days
30 * 36 = 1080 boy days
We have 10 men and 12 boys to do the job
We replace the 10 men with 15 boys
We have 15 boys and 12 boys for a total of 27 boys to do 1080 boy days worth of work
27 * day = 1080 boy days
days = 1080 /27
days = 40

Step-by-step explanation:

In this experiment there are 10 possible results for each event, therefore the distribution inst binomial. The correct answer therefore is C.
