Total no.of workers = 25
No.of pizzas delivered by 25 workers = 175
No.of pizzas delivered by each worker = 175/25 = 7
If 5 workers have fallen sick, then total no.of workers at present are 20.
Then total no.of pizzas delivered by 20 workers is {175+(175×25%)} = 218.75
No.of pizzas delivered by each worker at present is 218.75/20 = 10.9375
then required probability is 10.9375/218.75=0.05
option b is the correct answer
