Answer:
Step-by-step explanation:
Since the actual probability of having a boy child is 0.51, the probability of having a girl child will be (1 - 0.51) = 0.49
A couple plans to have 3 kids; 2 of whom are boys
(A) Using the binomial model, the probability that 2 of the 3 children will be boys is (2/3) × 0.51 = 0.34
(B) The possible orderings of the 3 children are given below:
B1 B2 G / B1 G B2
B2 B1 G / B2 G B1
G B1 B2 / G B2 B1
Where B1 is one male child and B2 is the other male child
(C) If we wanted to calculate the probability that a couple who plans to have 8 kids will have 3 boys, briefly describe why the approach from part (b) would be more tedious than the approach from part (a)
If the probability of 2/3 is 0.34 then the probability of 3/8 will be 0.1912 when you cross multiply
B: -(x^2) reflects over the x-axis and +3 shifts it up by 3
Step-by-step explanation:
4x-2y = 9 ...1
2x-y = -6 ...2
if ...2 × 2
4x-2y = -12
9 is not equal to -12
