An insurance company divides its policyholders into low-risk and high-risk classes. 60% were in the low-risk class and 40% in th

AleksAgata [21]

Answer:

a). 0.294

b) 0.11

Step-by-step explanation:

From the given information:

the probability of the low risk = 0.60

the probability of the high risk = 0.40

let $C_o$ represent no claim

let $C_1$ represent 1 claim

let $C_2$ represent 2 claim :

For low risk;

so, $C_o$ = (0.80 * 0.60 = 0.48), $C_1$ = (0.15* 0.60=0.09), $C_2$ = (0.05 * 0.60=0.03)

For high risk:

$C_o$ = (0.50 * 0.40 = 0.2), $C_1$ = (0.30 * 0.40 = 0.12) , $C_2$ = ( 0.20 * 0.40 = 0.08)

Therefore:

a), the probability that a randomly selected policyholder is high-risk and filed no claims can be computed as:

$P(H|C_o) = \dfrac{P(H \cap C_o)}{P(C_o)}$

$P(H|C_o) = \dfrac{(0.2)}{(0.48+0.2)}$

$P(H|C_o) = \dfrac{(0.2)}{(0.68)}$

$P(H|C_o) = 0.294$

b) What is the probability that a randomly selected policyholder filed two claims?

the probability that a randomly selected policyholder be filled with two claims = 0.03 + 0.08

= 0.11

Answer:

f(-121) = -5

f(31) = 3

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Function Notation

Step-by-step explanation:

Step 1: Define

f(x) = ∛(x - 4)

f(-121) is x = -121

f(31) is x = 31

Step 2: Evaluate

f(-121)

Substitute in x: f(-121) = ∛(-121 - 4)
[Radical] Subtract: f(-121) = ∛(-125)
[Radical] Evaluate: f(-121) = -5

f(31)

Substitute in x: f(31) = ∛(31 - 4)
[Radical] Subtract: f(31) = ∛27
[Radical] Evaluate: f(31) = 3
