I believe this problem has 3 questions:
a. Explain why the three conditions are satisfied for X to have
the binomial distribution.
b. Identify n and p for the binomial distribution.
c. Find the probability that the family has two girls and
two boys.
Answers:
a. First because there are only 2 possible outcomes for
each birth: male or female. Hence a binomial distribution. <span>
Second, because the probability of giving out a girl is
constant: 0.49 for each birth.
Third, the probability of a giving out a girl does not depend
on whether or not there is already a boy or a girl in the family. </span>
b. The n is the total number of children, so n = 4
While the p is the success of being a girls, so P = 0.49
c. We use the binomial probability equation:
P (X) = nCx * p^x * q^(n-x)
<span>P(X=2) = 4!/(2!2!) * 0.49^2 * 0.51^2 = 0.3747</span>
Answer:
Another expression: 9*(4a - 3)
Step-by-step explanation:
Though 36a - 27 is the simplest form we can factor it
36a - 27 = 9* (4a - 3)
3y=−4x+2
y = -4x/3 + 2/3
y = 3x/4 + 2/3
so the slope is 3/4 remember that perpendicular slope is just the opposite reciprocal of the original slope given.
560 - 164 = 396
396 / 3 = 132....each of the 3 crew members received $ 132
Raymond and Shauna must convince at least 5 more city council member. Because if every 2/6 members agree with the idea, then there would be 8 people out 24 that already agree with the idea. So if you have already 8 members then to make 13, you just need 5 (8 + 5=13) more people to 13.
