A certain genetic trait affects, independently, 30% of progeny; if 5 progeny are selected at random what is the probability that exactly 3 have the genetic trait
Homework Answers
Let x be a random variable = x = no of progeny affected out of 5
where x 
Po(5 * 0.30) = Po(1.5)
ANS : Probability that exactly 3 have genetic trait = 0.12551

A. According to an airline, flights on a certain route are independently of each other with an on-time rate of 80% of the time. Suppose 15 flights are randomly selected and the number of on time flights is recorded. How many total outcomes are available, if the order of the flights is considered? B. According to an airline, flights on a certain route are independently of each other with an on-time rate of 80% of the time. Suppose 15 flights...

Suppose a genetic trait in Impalas (Aepyceros datoadeni) occurs more often in males. The sex ratio in impalas is bout 50 males to 100 females. 80% of males have this trait, but only 15% of females. (a) What is the probability that a randomly chosen impala will have the trait? (b) Suppose a randomly picked impala has the trait (i.e., you pick an impala without paying attention to the sex), what is the probability this impala is a female?
