"The intersection (∩) of a pair of sets (G and H) is a third set (I) composed by the elements that belong, at the same time, to both given sets."
According to this definition:
Given the sets:
G = {3, 7, 8, 9}
H = {2, 5, 7, 8}
The Intersection is:
G ∩ H = I = {7, 8}

Step-by-step explanation:
When deciding where to put an ordered pair on a graph its important to understand how ordered pairs work. 
An ordered pair is split up into to pieces
(x,y) or number example (3,5)
When graphing the x coordinate will fall on your horizontal line or the line that looks like the horizon. 
When graphing the y coordinate it will fall on your vertical line or the line that goes right up into the sky like a rocket.  
To graph (3,5) 
Go to the right 3 and up 5 
Sometimes helps to use both fingers to keep your spot. Slide both fingers until they collide and that's where you would plot your point! 
Hope this helps if you have an questions just comment and ill try to explain further.

Answer:
A. 64/125
B. 124/125.
Step-by-step explanation:
A).  As the events ( germinate or not germinate) are independent we multiply the probabilities.
Prob(All seeds germinate) = 4/5*4/5*4/5 =  64/125.
B). Probability of at least one germinating =  1 - probability that none germinate
Probability of  1 seed not germinating = 1 -45 = 1/5.
So Prob(at least one germinating)
= 1 - (1/5 * 1/5 * 1/5)
= 1 - 1/125
= 124/125.
