Binomial Probabilities What does it mean to say that the trials of an experiment are independent?

Step-by-step explanation:

If I remember this correctly, if things/trials are independent then the result/outcome of one trial does not interfere or affect the outcome of other trials.

For example if you flip a coin 50 times. Each flip should be theoretically independent i.e. each head and tail should have 1/2 chance of showing up no matter what flip you make. It would not be independent if getting tails will give you heads next round for sure (it could happen by chance) but if one thing is causing another thing to happen it is not independent.  Which means the probability of a coin coming up heads does not depend in any way on previous coin flips. The chance of getting tails on the next coin flip should be 1/2 as well.

step-by-step explanation:

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
