Global Airlines operates two types of jet planes: jumbo and ordinary. On jumbo jets, 25% of the passengers are on business while
MArishka [77]

Answer:

Answer:

The  probability is  P(J|B) =  0.36

Step-by-step explanation:

B =business

J=jumbo

Or =ordinary

From the question we are told that  

     The proportion of the passenger on business in the ordinary jet  is P(B| Or) =  0.25

     The proportion of the passenger on business in the jumbo jet  is  P(B|J)  =  0.30

     The  proportion of the passenger on jumbo jets is  P(j) = 0.40

      The   proportion of the passenger on ordinary jets is evaluated as

         1 - P(J) =  1- 0.40  =  0.60

According to  Bayer's theorem the probability a randomly chosen business customer flying with Global is on a jumbo jet is mathematically represented as

        P(J|B) =  \frac{P(J) *  P(B|J)}{P(J ) *  P(B|J) +  P(Or ) *  P(B|Or)}

substituting values

         P(J|B) =  \frac{ 0.4 *   0.25}{0.4 *  0.25 +  0.6 * 0.3}

         P(J|B) =  0.36
