To calculate the number of shingles, we first calculate for the total area of the roof of Janice's house. From the figure, we can calculate the area of the two shapes: pyramid and a rectangular prism.
A(pyramid) = lw+l√[(w/2)²+h²]+w√[(l/2)²+h²]
A = 208 m²
A(prism) = 2(wl+hl+hw)
A = 293 m²
Total area = 501 m²
Number of shingles she needs = 501 m² / 2.25 m² =<span> 223</span><span>

Answer:
The correct answer is 0.0330 and the events are independent.
Step-by-step explanation:
Total number of balls in Bill's golf bag = 17
Let A be the event of drawing a white ball and B be the event of drawing an orange ball.
Number of white balls Bill has in his bag is 9.
Probability of the event A in the first draw = 
Number of orange ball in Bill's bag is 1.
Probability of event B in the second draw = 
Thus total probability for Tim to tee off with a white ball and putt with an orange ball =
= 0.0330
The above events are independent on each other.
