Step-by-step explanation:

87 for t-shirts and 243 for sweatshirts, the total cost is 330
Answer:
The two conditional probabilities are not equal because each has different given events. P(A|D) has event D as its given event, resulting in 2/10 for a probability. P(D|A) has event A as its given event, resulting in 2/8 for a probability.
Other part is:
different given events
P(A|D) equals 2/10
P(D|A) equals 2/8
Answer:
(5,0)=x1,y1
(0,3)=x2,y2
so the range will be x1-x2/
