Which probability is relevant for determining whether 1 is a significan Question Viewer girls in 8 births: the result from part (a) or part (b)? O A. Since getting 0 girls is an even lower number of girls than getting 1 girl, the result from part (b) is the relevant probability. O B. Since the probability of getting 1 girl is the result from part (a), this is the relevant probability. OC. Since the probability of getting more than 1 girl is the complement of the result from part (b), this i the relevant probability. O D.
