Atest to determine whether a certain antibody is present is 99.1% effective. this means that the test will accurately come back negative if the antibody is not present (in the test subject) 99.1% of the time. the probability of a test coming back positive when the antibody is not present (a false positive) is 0.009. suppose the test is given to six randomly selected people who do not have the antibody. (a) what is the probability that the test comes back negative for all six people? (b) what is the probability that the test comes back positive for at least one of the six people?

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 ?
