the probability of rain on any given day is 2/3 . what is the probability of at most one day of rain during the next three days?

Step-by-step explanation:

Let the event of raining on a day be success.

Then probability of success,

So, probability of failure is not raining on a day and is given as,

Now, number of days to check the probability of rain,

Now, probability of raining at most one day means number of success is either 0 or 1.

Using Bernoulli's distribution for

Therefore, the probability of at most one day of rain during the next three days is

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

i’m sorry but i don’t know sorry
