A high school senior applies for admission to two colleges A and B, and suppose that:
P(admitted at A)=p1, P(rejected by B)=p2, and P(rejected by at least one, A or B)=p3.
(i) Calculate the probability that the student is admitted by at least one college.
(ii) Find numerical value of the probability in part (i), if p1=0.6, p2=0.2, and p3=0.3.

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
