Starting at a fixed time, we observe the gender of each newborn child at a certain hospital until a boy (b) is born. assume that successive births are independent and let y = the number of girls born before the experiment terminates. with p = p(b)and 1 − p = p(g), what is the pmf of y? [hint: first list the possible values of y, starting with the smallest, and proceed until you see a general formula.] (enter your answer in terms of p and y.)

p(y) = y = 0, 1, 2, 3, 4,

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3

answer: the is put the 450

step-by-step explanation:

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
