You refer to a rectangular distribution.
I.e. Area ∝ probability
so, length x height = area
=> 6 x height = 1
so, height = 1/6
Therefore, greater than 2.25 minutes => 8-2.25 = 5.75 minutes
=> 5.75 x 1/6 = 0.9583
Since this is uniformly distributed, there is no need to
find the height or standard deviation.
The equation of a line can be expressed in slope intercept form as y = mx + b where m is the slope and b is the y-intercept. Horizontal lines have a slope of 0, so the equation is simply y=b.
The y value of the point given is -5, so the answer is y = -5.
Answer: 
Step-by-step explanation:
Let's look at the numbers that we count.
The question says not multiple of 2, so we have to count to following numbers:
1 , 3 , 5
And in total there are 6 numbers, so our probability is
=
1/4 = 2/8... So:
3/8 - 2/8 = 1/8
