Maurinko [17]

Answer:

the probability is 0.12 ( 12%)

Step-by-step explanation:

Defining the following events F= the dollar falls in value against the Japanese yen in the next month and the event R=the supplier will demand renegotiation of the contract , then we can apply conditional probability using the theorem of Bayes :

P(R∩F)=P(F)*P(R/F)

where

P(R∩F)= probability that the supplier will demand renegotiation of the contract and the dollar falls in value against the Japanese yen in the next month

P(R/F) =  probability that the supplier will demand renegotiation of the contract if the dollar falls in value against the Japanese yen in the next month

then replacing values

P(R∩F)=P(F)*P(R/F) = 0.2 * 0.6 = 0.12

therefore the probability is 0.12 ( 12%)
