0.18519
Step-by-step explanation
Suppose A is an event. P(A) or the probability that A will occur is given by
P(A)=total number of outcomesnumber of favorable outcomes to A?.
Let A = event that out of 27 patients a therapist would randomly get the 5 with the highest measures. By the theorem above, the number of favorable outcomes to A is 5 and the total number of outcomes is 27. So
P(A)=275?
P(A)=0.1851851852
P(A)=0.18519
