ABC Company prints text books. They use two modes of transportation to ship, rail and truck. In the 20 years during which they have operated, only 2 percent of the packages carried by rail and only 3.5 percent of the packages carried by truck have been lost. The claims manager receives a call and is informed that a package containing text books sent by ABC Company has been lost. ABC sends 60% of the packages by rail and 40% by truck. The text books are indeed lost. What is the probability the text books were shipped by truck

53.85% probability the text books were shipped by truck

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Textbooks lost.

Event B: Shipped by truck.

40% of the packages sent by truck.

This means that

3.5 percent of the packages carried by truck have been lost.

This means that

Probability package is lost:

60% probability it is sent by rail. Of those, 2% are lost.

40% sent by truck. Of those, 3.5% are lost.

So

What is the probability the text books were shipped by truck

53.85% probability the text books were shipped by truck

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
