Let x = Number of water bottles
y = Number of hats
The club wants to raise $1200.
i.e. Required equation : 4x+6y=1200
At x=0,
At x= 300
At x= 240
So,three ordered pairs(x,y) that exist on the line : (0,200), (300,0) and (240,40)
Plot these point on graph and join them.

Step-by-step explanation:
Given : P(A) = 0.3 and P(B) = 0.6
To Find:P(A or B) = P(A∪B)
Solution :
We are given that A and B are two independent events
Property : If A and B are independent events then
So,
Formula :
Hence P(A or B) is 0.72
