I think maybe it's A. sorry if that's wrong
You are probably expected to choose ...
• All integers are rational numbers.
• Terminating decimals are rational numbers.
However, the premise of ...
• 0.278254….. is a terminating decimal, therefore it is a rational number.
is False, so the rules of logic allow any conclusion—meaning the implication is True. (As it happens, a repeating decimal is, in fact, a rational number.) So, this, too, is a true statement.
Ans: Option (D) 25%
Explanation:
In this case you need to find the area under the curve, which would essentially be the probability of a value in the sample space.
Now the range given is from 60 to 80; it contains the mini-triangle.
The area of the triangle = (1/2)*base*height
Since base = 80 - 60 = 20
Height = 0.025 - 0 = 0.025 (see in the graph)
Therefore
The area of the triangle = 1/4 = 0.25 which is essentially be the probability.
In percentage form, it is 25% (Option D)
