4. Automobile policies are separated into two groups: low-risk and high-risk. Actuary Rahul examines low-risk policies, continui
ANTONII [103]

Answer:

Step-by-step explanation:

for n ∈ N

Since Actuary Rahul examines low-risk policies, continuing until a policy with a claim is found and then stopping.

∴ the probability that Actuary Rahul examines exactly n policies

(0.9)^{n-1}.(0.1)---(1)

the probability that Actuary Toby examines more than  exactly n policies

(0.8)^n---(2)

Given that policies are actually independent

∴ the probability that the event  (1) and (2) happens simultaneously is

(0.9)^{n-1}*(0.1)*(0.8)^n

∴  the probability that Actuary Rahul examines fewer policies than Actuary Toby

\sum ^\infty _{n=1} (0.9)^{n-1}*(0.1)*(0.8)^n\\\\=(\frac{0.1}{0.9} \sum ^\infty _{n=1}(0.72)^n\\\\=\frac{1}{9} (\frac{0.72}{0.28} )\\\\=\frac{2}{7} \\\\=0.2857

<h3>the probability that Actuary Rahul examines fewer policies than Actuary Toby is 0.2857</h3>
