Answer:
Step-by-step explanation:
a) If events A and B are independent we have
P(A/B) =P(A)
But here P(A/B) = 0.8 and P(A)=0.2
Hence A and B are not independent.
b) If events A and B are independent we have
P(A/B) =P(A)
But here P(A/B) = 0.6 and P(A)=0.3
Hence A and B are not independent.
c) If events A and B are independent we have
P(A/B) =P(A)
Jere P(A/B) = 0.5 and P(A)=0.5
Hence A and B are independent.
Answer:
Step-by-step explanation:
The drawing of the garage is a smaller representation of the actual garage. A garage is drawn using a scale of 2 2/3 inch = 6feet. Let us first convert 2 2/3 inch to improper fraction. It becomes 8/3 inch.
Let us determine the unit measurement.
If 6feet = 8/3 inch,
1 foot will be 8/3 ÷ 6 = 8/3×1/6
= 8/18 inches. Therefore
if the actual height is 68 ft , then, the height of the garage on the drawing will be
68 × 8/18 = 272/9 = 30 2/9 inches
