Step-by-step explanation:
Given that the probability of mail being delivered is 0.90, to evaluate the probability that the mail will be delivered before 2 p.m for 2 consecutive days will be evaluated as follows:
Let the probability that the milk will be delivered before 2 p.m be P(x). Since the two days are independent events, the probability of the mail being delivered before 2 p.m in 2 consecutive days will be:
P(x)×P(x)
=0.9×0.9
=0.81
Answer:

Step-by-step explanation:
The simple interest is calculated only on initial amount deposited and so the interest per year is constant.
Let the initial amount be "x".
The interest for first n years is,

and so the final amount is

Similarly for n-1 years,
interest is = 
and amount is ,
A2 = x + 
The required ratio is ,
