If it is not binomial, identify the requirements that are not satisfied. We assume that we know nothing about these 50 adults' music taste before asking A. No, because there are more than two possible outcomes and the trials are dependent. B. No, becoause the probability of succes does not remain the sae in all tials C. No, because there are more than two possible outcomes. D. Yes, because all 4 requirements are satisfied. (0) (2 points) Which of the following values are not probabilities (choose ALL answers that apply)? A. 8:7 C. 4/3 D. 0 E. 1 (8) (2 points) A couple is giving birth to three babies. Assuming that boys and girls are equally likely, what is the probability that among those three babies at least one is girl? B. C. D. E.Explanation / Answer
e
as the answers are yes or no . so it can take only 2 values , also the probability for each trial remains the same , However there can be one more option - that is - dont know
Hence C
f
probabilities can range from 0 to 1 only , hence a , b and c are not possible
g
boys and girls are equally likely so prob is 1/2
3 babies , atleast 1 is girl
so
1/2*1/2*/2 = 1/8
