.....help with questions a-d please.

b. Find the probability of getting 1 or fewer girls in 8 births.

(Type an integer or a decimal. Do not round.)

c. Which probability is relevant for determining whether 1 is a significantly low number of girls in 8 births: the result from part (a) or part (b)?

A. Since the probability of getting more than 1 girl is the complement of the result from part (b), this is the relevant probability.

B. Since getting 0 girls is an even lower number of girls than getting 1 girl, the result from part (b) is the relevant probability.

C.Since the probability of getting 0 girls is less likely than getting 1 girl, the result from part (a) is the relevant probability.

D.Since the probability of getting 1 girl is the result from part (a), this is the relevant probability.

D. Is 1 a significantly low number of girls in 8 births? Why or why not? Use 0.05 as the threshold for a significant event.

A.No, since the appropriate probability is less than 0.05, it is not a significantly low number.

B.Yes, since the appropriate probability is greater than 0.05, it is a significantly low number.

C.No, since the appropriate probability is greater than 0.05, it is not a significantly low number.

D.Yes, since the appropriate probability is less than 0.05, it is a significantly low number.
