A real estate agent has 17 properties that she shows. She feels that there is a 30% chance of selling any one property during a week. The chance of selling any one property is independent of selling another property. Compute the probability of selling more than 5 properties in one week. Round your answer to four decimal places.

 0.4032

If it served you, give me 5 stars please, thank you!

solution:-

given that p = 0.30 , n = 17

p(x > 5) = 1 - p(x ≤ 5)

= 1 - (p(x = 5) + p(x = 4)+ p(x = 3)+ + p(x = 2)+ p(x = 1)+ p(x = 0))

= 1 - (0.2081+0.1868+0.1245+0.0581+0.0169+0.0023)

= 1 - 0.5968

= 0.4032

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
