3. Given X and Y are two events such that P(X) = 5,P(Y) = and P(Xn Y) = . Find P(Y|X).
4. A firm has 500 workers. As many as 80% of them play football, 75%
play hockey, 50% rugby and 36% play all the three games. 35 of the
workers play only football and 32 of them play only hockey while 203 of them play both hockey and rugby .Show allvthe information clearly in a Venn diagram . if a worker is selected at randon, what is the probability that he / she plays football given that he/she also plays hockey?

yes

step-by-step explanation:

yes

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
