Answer:
Step-by-step explanation:
Given that
A sample space consists of five simple events, E1, E2, E3, E4, and E5.
a If P(E1) = P(E2) = 0.15,
P(E3) = 0.4, and P(E4) = 2P(E5),
We know that total probability =1
i.e. sum of probabilities of All Eis would be 1
where x = P(E5)
Solving for x we get
x=0.30
So P(E4) = 0.2 and P(E5) = 0.1
-----
b) Let P(E3) =P(E4) = P(E5) = y
then we have
total probability =
Probability of remain are 0.2 each.
Rounded to the nearest hundredth, numbers look like this:
So, our number lies between 0.62 and 0.63. We have to check which of the two is closer. To measure the distance between numbers, we use the absolute value of the difference:
Since , we deduce that 0.63 is closer to 0.6288 than 0.62, and thus it's a better approximation.

Answer
After 13.15 years the population of both towns will become equal.
Step-by-step explanation:
Population of the city Anville is given by using the compound interest formula
The formula of compound interest
A = p( 1+r/n)^n*t
using this we get
P1 = 16000 (1 +) ^1*t
Population of the city of Brinker will be
P2 = 11000( 1 + ) ^1*t
now to make equal population in both towns
P1=P2
16000 (1 +) ^1*t = 11000( 1 +
) ^1*t
t = 13.15 years
