A. find the probability of getting exactly 6 girls in 8 births. b. find the probability of getting 6 or more girls in 8 births. c. which probability is relevant for determining whether 6 is a significantly girls in 8 births: the result from part (a) or part (b)

Assuming each birth can give life to a boy or girl with equal chance, then the probability of having a girl is

The probability of having exactly six girls is given by Bernoulli rule:

As for the second point, let's compute the probabilty of having zero, one or two boys, which is the same of having six or more girls, but requires less calculations:

which simplifies to

Finally, I am not sure of what you mean with the point c, so please clarify the question.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
