At a party n men throw their hats into the center of a room. The hats are mixed up and each man randomly selects one. If a person selects his own hat, we call this a match. (i) Find the expected number of men who selected their own hats. (ii) Find the conditional number of matches given that the first person did not have a match

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
