Savatey [412]

Answer:

P=0.3726 or 37.26%

Step-by-step explanation:

The success, with 41% of probability of occurring, is that the employee believes the ​ company's president possesses low ethical standards. For more than 8 and less than 12 successes, it means the probability of having  9, 10 or  11 successes (all these summed).

The formula is:

b(x;n,p)= \ _nC_x*p^x*(1-p)^{n-x}

Where x is the number of successes,n the number of trials, p the probability of success,_nC_x refers to the combinations that can occur,  and it's formula is:

_nC_x=\frac{n!}{x!(n-x)!}

Calculating each case:

b(9,20,0.41)=\frac{20!}{9!(20-9)!}*0.41^9*(1-0.41)^{20-9}=0.1658

b(10,20,0.41)=\frac{20!}{10!(20-10)!}*0.41^{10}*(1-0.41)^{20-10}=0.1267

b(11,20,0.41)=\frac{20!}{11!(20-11)!}*0.41^{11}*(1-0.41)^{20-11}=0.0801

Adding each case:

P=0.1658+0.1267+0.0801= 0.3726
