Why is probability limited to numbers between 0 and 1​

Mathematics

3 0

Answer:

Probability by definition is the extent to which an event is likely to occur, measured by the ratio of the favourable cases to the whole number of cases possible.

Since number of elements in the set of favourable cases is less than or equal to the number of elements in the set of whole number of cases, their ratio would always end up being 1 or less than one.

Probability equals one when favourable number of cases are same as that of the whole number of cases and probability equals zero when there is no favourable case

Find the point, M, that divides segment AB into a ratio of 4:7 if A is at (-33, 0) and B is at (0, 44).
insens350 [35]
Let's say the point is C, and divides AB on a 4:7 ratio, from A to B, meaning the AC segment takes 4 units of the lot and the CB segment takes 7.

\bf ~~~~~~~~~~~~\textit{internal division of a line segment}
\\\\\\
A(-33,0)\qquad B(0,44)\qquad
\qquad \stackrel{\textit{ratio from A to B}}{4:7}
\\\\\\
\cfrac{A\underline{C}}{\underline{C} B} = \cfrac{4}{7}\implies \cfrac{A}{B} = \cfrac{4}{7}\implies 7A=4B\implies 7(-33,0)=4(0,44)\\\\
-------------------------------

\bf C=\left(\cfrac{\textit{sum of "x" values}}{\textit{sum of ratios}}\quad ,\quad \cfrac{\textit{sum of "y" values}}{\textit{sum of ratios}}\right)\\\\
-------------------------------\\\\
C=\left(\cfrac{(7\cdot -33)+(4\cdot 0)}{4+7}\quad ,\quad \cfrac{(7\cdot 0)+(4\cdot 44)}{4+7}\right)
\\\\\\
C=\left( \cfrac{-231+0}{11}~~,~~\cfrac{0+176}{11} \right)\implies C=(-21~,~16)

A motorcycle can travel 70 miles per gallon. Approximately how many gallons of fuel will the motorcycle need to travel 60 km?
cricket20 [7]
We have the following given
mileage = 70 miles per gallon
distance = 60 km

Required: amount of fuel in gallons

First, we must convert the distance to miles, so
60 km (1 mi/1.6 km) = 37.5 mi

So, the amount of fuel is
37.5 mi / (70 mi/gal) = 0.54 gallons
