How To Resolve a Car Accident Using Bayesian Theorem?

687 Views Asked by At

The probability that a one-car accident is due to faulty brakes is $0.04$, the probability that a one-car accident is correctly attributed to faulty brakes is $0.82$, and the probability that a one-car accident is incorrectly attributed to faulty brakes is $0.03$. What is the probability that

$(a)$ a one-car accident will be attributed to faulty brakes;

$(b)$ a one-car accident attributed to faulty brakes was actually due to faulty brakes?

Is my interpretation of this problem correct? If so can I continue and use the Rule of total probability and conditional probability?

$B_{1} = \{ \text{Car accident due to faulty brakes \}}$

$B_{2} = \{ \text{Car accident NOT due to faulty brakes \}}$ (refers to elements not in $B_{1}$)

$P = \{ \text{attributed to brakes}\}$

$N = \{ \text{NOT attributed to brakes}\}$

$P(B_{1}) = .04 \; \; \;P( B_{2})= .96$

$P(P|B_{1}) = .82$

$P(P|B_{2}) = .03 $

$P(N|B_{1}) = 1-.82 =.18$

$P(N|B_{2}) = 1-.03 = .97 $
