A new surgical procedure is successful with probability of p. Assume that the operation is performed 5 times and the results are

DaniilM [7]

Answer:

a) $P(X=5)=(5C5)(0.8)^5 (1-0.8)^{5-5}=0.32768$

And we can use the following excel code: "=BINOM.DIST(5,5,0.8,FALSE)"

b) $P(X=4)=(5C4)(0.6)^4 (1-0.6)^{5-4}=0.2592$

And we can use the following excel code: "=BINOM.DIST(4,5,0.6,FALSE)"

c) $P(X$

And the excel code would be: "=BINOM.DIST(1,5,0.3,TRUE)"

d) $E(X) =n*p= 5*0.5 =2.5$

e) $Var (X) = np(1-p) = 5*0.4*(1-0.4)=1.2$

Step-by-step explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest, on this case we know that:

$X \sim Binom(n=5, p)$
