Step by step solution

01

Step 1. Given Information

The table is:

02

Step 2. Concept Used

Formula used: Probability=NumberoffavorableoutcomesTotalpossibleoutcomes

03

Step 3. Calculation

P(E|L) and P(L|E)

are calculated as:

P(E|L)=8002268+800+588=0.219

P(F|L)=800368+432+800=0.50

The probabilities necessary are 0.219and 0.50, respectively. It is necessary to compare these two estimated probabilities in order to arrive at a conclusion.
