Suppose that Juan can choose to get home from work by car or bus. When he chooses to get home by car, he arrives home after 7 p. m. 14 percent of the time.

When he chooses to get home by bus, he arrives home after 7 p. m. 62 percent of the time.

Because the bus is cheaper, he uses the bus 83 percent of the time.

What is the approximate probability that Juan chose to get home from work by bus, given that he arrived home after 7 p. m.?

Exercise: counting committees 0.0/2.0 puntos (calificable) we start with a pool of n people. a chaired committee consists of k≥1 members, out of whom one member is designated as the chairperson. the expression k(nk) can be interpreted as the number of possible chaired committees with k members. this is because we have (nk) choices for the k members, and once the members are chosen, there are then k choices for the chairperson. thus, c=∑k=1nk(nk) is the total number of possible chaired committees of any size. find the value of c (as a function of n ) by thinking about a different way of forming a chaired committee: first choose the chairperson, then choose the other members of the committee. the answer is of the form c=(α+nβ)2γn+δ. what are the values of α , β , γ , and δ ?
