A couple plans to have three children. Each child is equally likely to be a girl or boy, with gender independent of that of the other children. a. Construct a sample space for the genders of the children, using B for boy and G for girl. b. Find the probability that all 3 of the children are boys. c. Answer part b if, in reality, for a given child, the chance of a boy is 0.51.

from the sentence, "tomorrow morning, akiko will arrive an hour late" depicts a third person perspective because it doesn't use any pronoun to replace akiko, the subject of the sentence, and it is in singular form since akiko is only one person.

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
