Answer:
Step-by-step explanation:
If each day equal chance then p = Prob that a person is borne on a particular day = 1/365
Each person is independent of the other and there are two outcomes either borne in July or not
p = prob for one person not borne in July = (365-31)/365 = 334/365
a)Hence prob that no one from n people borne in July = 
b) p = prob of any one borne in July or Aug =
=0.1698
X- no of people borne in July or Aug
n =15
P(X>=2) =
=0.7505
If the original price is 16, then 3/4 of 16 is 12.
$12
Dividing 16 by 4 (the denominator), you get 4. Then 4 x 3 (the numerator) is 12.
Do your sum which is $329.69 subtract $59.63 then if the unit is 4 or less round your answer to the nearest ten eg, 103 would be rounded to 100. If the unit is 5 and above you would round your answer up eg, 437 would be rounded to 440.
