We assume that male and female births are equally likely, it means that the probability of birth of male= probability of birth of female = 100%/2=50% or 0.5We have 2 independent events. So what will be the variants:
Male and FemaleMale and Male Female and Male Female and Female
All four variants are equally likely.Probability of each one is 1/4 = 0.25.So, Result "Female and Female"
are probability = 0.250 --- if round to three decimal places.
I think it would be the third option. I jiust guessed.
I'm not sure if this is the answer but 16km is 9.94 miles. 33 divided by 5 is equal to 6.6. 33 divided by 9.94 is about 3.3199 . So Lisa would have the greatest average. Hope this helped!
