# Show work for everything, plus an explanation, if you could you.

1. is it possible to use the formula p(a and b) = p (a) x p (b|a)when events a and b are independent? explain your reasoning.

2. according to a survey, about 58% of families sit down for a family dinner at least four times per week. you ask 5 randomly chosen families whether they have a family dinner at least four times per week.

a)draw a histogram of the binomial distribution for the survey.

b)what’s the most likely outcome of the survey?

c)what’s the probability that at least 3 families have a family dinner four times per week?

3. the surface area of the earth is about 196.9 million square miles. the land area is about 57.5 million square miles and the rest water. what’s the probability that it will hit the water?

4. three volunteers are chosen at random from a group of 12 to .

a)what’s the probability that you, your friend and your brother is chosen?

b)what’s the probability that you are the cook, your brother the lifeguard, and your friend the counselor? (the first person chosen will be counselor, second will be lifeguard, and third will be the cook.)

In δabc shown below, ∠bac is congruent to ∠bca: triangle abc, where angles a and c are congruent given: base ∠bac and ∠acb are congruent. prove: δabc is an isosceles triangle. when completed (fill in the blanks), the following paragraph proves that line segment ab is congruent to line segment bc making δabc an isosceles triangle. (4 points) construct a perpendicular bisector from point b to line segment ac . label the point of intersection between this perpendicular bisector and line segment ac as point d: m∠bda and m∠bdc is 90° by the definition of a perpendicular bisector. ∠bda is congruent to ∠bdc by the definition of congruent angles. line segment ad is congruent to line segment dc by by the definition of a perpendicular bisector. δbad is congruent to δbcd by the line segment ab is congruent to line segment bc because consequently, δabc is isosceles by definition of an isosceles triangle. 1. corresponding parts of congruent triangles are congruent (cpctc) 2. the definition of a perpendicular bisector 1. the definition of a perpendicular bisector 2. the definition of congruent angles 1. the definition of congruent angles 2. the definition of a perpendicular bisector 1. angle-side-angle (asa) postulate 2. corresponding parts of congruent triangles are congruent (cpctc)
