.2.9 HW Score : 37 04%, 6 67 of 18 3 Assigned Media Question Help Assume that 100 births are randomly selected and exactly 40 of the births are giris. Use subjective judgment to deterinine whether the given outcome is unilkely and also determine whether it is unusual in the sense that the result is far from what is typically expected Determine whether exactly 40 girls out of 100 randomly selected births is unlikely A ?t is unlikely because the probability of this particular outcome is very small considering all of the other possible outcomes OB. It is not unilikely because girls are slightlyless common than boys O C. It is not unlikely because 40 is about half of 100 O D. It is unlikely because it is not 50 as expected cHck to select your answer and then click Check Answer impossible to get 8 aces when

Explanation / Answer

From the given information, out of 100 randomly selected births, exactly 40 are girls. So, P(girl) = 40/100 = 0.4

If 100 random births are selected, then the probability that exactly 40 are girls = 100C40*(0.4)40*(0.6)60 = 0.08.

Since, P(exactly 40 girls) = 0.08, which is very less compared to other possible outcomes, it is unlikely to happen. So, answer is option A.
