BRAINLIST and 100 Points!! 1) In a certain country, the probability that a baby that is born is a boy is 0.55 and the probability that a baby that is born is a girl is 0.45. A family has two children. If X is the number of girls born to a family, find the probability that the family has 0,1, or 2 girls.
(a) Draw a tree diagram showing the possibilities for each outcome.
(b) Creat the binomial distribution table for P (X).

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb

its a, i had the same answer, its from study island right

step-by-step explanation:

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.
