. Upon arrival at a hospital’s emergency room, patients are categorized according to their conditions as critical, serious, or stable. In the past year, 10% were classified as critical, 30% serious, and the rest were stable. The records of 12 emergency room patients are randomly chosen to be examined for analysis. a) What is the probability that all 12 records were of patients classified as critical? Just help me set it up. i don't want the exact answer.

    The probabilty os one patient is crassified as critical is 0,1 (10%/100%) The probability of 12 patients to be critical is the firts critical AND the second critical, etc... So it is (0,1)^12

    p (.10)12= .0000000000001 would that be the answer?
