Answer:
0.07776, 0.3456,0.08704
Step-by-step explanation:
Given that a new surgical procedure is said to be successful 60% of the time
Let X be the no of successes
Then X has only two outcomes and each trial is independent of the other
Hence X is binomial with p = prob of success in a single trial = 0.60
n = Number of operations performed = 5
Prob that
a) all five operations are successful =

(b) exactly three are successful
=
(c) less than two are successful

Answer:
yes

Answer:
n = - 10
Step-by-step explanation:
10(-3n + 8) = 380
-30n + 80 = 380
80 - 380 = 30n
30n = - 300
n = - 300 : 30
n = - 10
