Complete parts (a) through (d) below. Click the icon to view the table. C a. Find the probability of getting exactly 6 girls in 8 births. (Type an integer or a decimal. Do not round.) b. Find the probability of getting 6 or more girls in 8 births. (Type an integer or a decimal. Do not round.) c. Which probability is relevant for determining whether 6 is a significantly high number of girls in 8 births: the result from part (a) or part (b)? O A. The result from part a, since it less than the probability of the given or more extreme result. O B. The result from part a, since it is the exact probability being asked. O C. The result from part b, since it is the complement of the result of part a O D. The result from part b, since it is the probability of the given or more extreme result. d. Is 6 a significantly high number…
