Suppose that we have a sample space s={e1,e2,e3,e4,e5,e6,e7}, where e1 to e7 denote the sample points. the following probability assignments apply: p(e1 )=.05 p(e2)=.20 p(e3)=.20 p(e4)=.25 p(e5)=.15 p(e6)=.10 and p(e7)=.05let a={e1,e4,e6} b={e2,e4,e7} c= {e2,e3,e5,e7}a) find p(a), p(b) and p (c)b) find a u b and p (a u b)c) find bc and p(bc)

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

b

step-by-step explanation:

this is because the profit is decreasing and turning into debt
