In a study, the various stages of sleep for a large group of people were monitored in 30-second intervals, or "epochs." For each epoch, sleep stage was categorized as
Wake, REM, or Non-REM. The accompanying table provides a summary of the results. Each cell of the table gives the number of epochs that occurred when
transitioning from the previous sleep stage to the current sleep stage. Complete parts a through e beloW.

a. Given that the previous sleep stage for the epoch was the REM state, what is the probability that the current sleep stage is REM?
The probability is
(Type an integer or a decimal. Round to three decimal places as needed.)
