expeople1 [14]

Answer:

P(X=2)=0.04129

Step-by-step explanation:

-This is a binomial probability problem whose function is expressed as;

P(X=x)={n\choose x}p^x(1-p){n-x}

-Given that p=0.6, n=8 , the probability that among the students in the sample exactly two are female is calculated as:

P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X=2)={8\choose2}0.6^2(1-0.6)^6\\\\=0.04129

Hence, the probability of exactly two females is 0.04129

OlgaM077 [116]

Answer:

54 as a percentage of 216% is 116.64.

Step-by-step explanation:

100% of 54 is 54 so 54 x 2 would be 108. We have solved 200% of it now for the 16%. The percentage of 54 of 16% would be 8.64. Now add up all we have learned.

108 + 8.64 = 116.64
