Two methods, A and B, are available for teaching a certain industrial skill. There is an 80% chance of successfully learning the skill if method A is used, and a 95% chance of success if method B is used. However, method B is substantially more expensive and is therefore used only 25% of the time (method A is used the other 75% of the time).

The following notations are suggested:

• AmethodAis used
• BmethodBis used
• Lthe skill wasLearned successfully

Question 2 of 5

Which of the following is the correct representation of the information that is provided to us?

P(A) = .75, P(B) = .25, P(L | A) = .80, P(L | B) = .95

P(A) = .75, P(B) = .25, P(A | L) = .80, P(B | L) = .95

P(A) = .75, P(B) = .25, P(A and L) = .80, P(B and L) = .95

P(A | L) = .75, P(B | L) = .25, P(L | A) = .80, P(L | B) = .95

P(A and L) = .75, P(B and L) = .25, P(L | A) = .80, P(L | B) = .95
