Answer:
Step-by-step explanation:
Given that a loan company knows that 5% of its loans will be delinquent.
since each loan is independent of the other p , probability for any random loan to be delinquent is constant 0.05
X no of delinquent loan accounts is binomial with n =400 and p = 0.05
Since n is very large and also np = 20 and nq >5 we can approximate to normal
Mean = np = 20 : Variance = npq = 19
Std dev = 4.36
X is N(1, 4.36)
With continuity correcton we calculate the prob
a) that exactly 25 accounts will be delinquent?
=
b) that fewer than 30 accounts will be delinquent?
=P(X<29.5)
= 0.9854
c) more than 24 accounts will be delinquent
=P(X>24,5)
=0.1509

Answer: a) 0.22 b) 0.1363
Step-by-step explanation:
People who contract disease I are= 10%
People who contract disease II are= 15%
People who contract both diseases are= 3%
a)
People who contract has at least one disease needs to be found out so it is given as
P(D1 or D2)= P(D1) + P(D2) - P(D1 and D2)
P(D1 or D2)= 10% + 15% - 3%
P(D1 or D2)= 22%
P(D1 or D2)= 0.22
b)
Conditional probability that randomly selected person will get get diseases given she has contracted at least one disease is gven as
Probability= P(D1 and D2) / P(D1 or D2)
Probability= 
Probability= 13.63%
Probability= 0.1363
The answer is 1180 dollars. You can just multiply 295 x4
