Let say that you want to take 1 area. Before the event, the probability of A and B would be:
A= blue and green= (18/12x6) + (18/12x6) = 36/72
B= green and yellow= (18/12x6) + (18/12x6) <span>= 36/72
</span>
If the area that picked is green, then the probability of A and B become
A= blue and green= (18/12x6-1) + (17/12x6-1) = 35/71
B= green and yellow= (17/12x6-1) + (18/12x6-1) = 35/71
Both of the areas of A and B is decreased because they share the probability of green. So A and B would be a dependent event.

Answer:
Step-by-step explanation:
Pythagorean Theorem: a^2+b^2=c^2.
15^2+ b^2=25^2
225+b^2= 625
b^2=400
b= 20 or x=20
0.14 * 55,000= 7,700
7,700 acres of the forest was destroyed
55,000-7,700=47,300
47,300 acres of the forest was not destroyed
15% of $9.00 equals $1.35.
