In a certain country, the true probability of a baby being a boy is 0.524. Among the next five randomly selected births in the
1 answer:
Answer:
The probability that at least one of them is a girl is 0.96049.
Step-by-step explanation:
In a certain country, the true probability of a baby being a boy is 0.524.
This is a binomial problem.
p(boy) = 0.524
n = 5
p(girl) =
P(at least one girl) = 1 - p(5 boys) = = 0.96049
Hence, the probability is 0.96049.

Answer:
P(x ≤ 5 ) = 0.9707
P ( x ≥ 6) = 0.0293
Step-by-step explanation:
The probability of a binomial mass distribution can be expressed with the formula:
where;
n = 8 and π = 0.36
For x = 5
The probability
to 4 decimal places
b. x ≤ 5
The probability of P ( x ≤ 5)
P(x ≤ 5 ) = 0.0281+0.1267+0.2494+0.2805+0.1972+0.0888
P(x ≤ 5 ) = 0.9707
c. x ≥ 6
The probability of P ( x ≥ 6) = 1 - P( x ≤ 5 )
P ( x ≥ 6) = 1 - 0.9707
P ( x ≥ 6) = 0.0293
