In a certain country, the true probability of a baby being a girl is 0. . . . Complementary probability: P(at least one boy) = 1 - P(all five girls) = 1 - 0 0221 ≈ 0 9779 Therefore, the probability that at least one of the next five randomly selected births in the country is a boy is approximately 0 9779, or 97 79%
Solved in a certain country, the true probability of a baby - Chegg In a certain country, the true probability of a baby being a girtis 0 489 Among the next seven randomly selected births in the country, what is the probability that at foast one of them is a boy? The probability (Round to three decimal places as needed )
In a certain country, the true probability of a baby being a girl is Now, the probability that at least one of them is a boy can be calculated in below: P at least one of them is a boy = 1-P 7 girls ⇒ P at least one of them is a boy = 1-0 476 7 ∴ P at least one of them is a boy = 0 9945 Hence, the probability that at least one of them is a boy is approx 0 9945
stats chapter 4: online HW Flashcards - Quizlet Here, the number of trials is 7, p is 0 476, q is 0 528, the number of successes x is 7, that is, getting all 7 girls in the next seven randomly selected births So, the probability of at least one boy using binomial distribution: the probability of a boy= 1-0 472= 0 528 the probability of only 7 successive girl births: p(X=7)= (0 476)^7 (0 528
