You randomly pick two numbers from 1 to 9 (including 1 and 9). A number that is chosen once could be chosen again. If at least o
Mnenie [13.5K]
Assume that you only include whole numbers (1,2,3,4,5,6,7,8,9) and not 3.5 and such
so if 1 is odd and less than 5 then it is
1 or 3, since 5 isn't included
then the other number, to be less than 5 when added,
must be
1+x<5
3+x<5
solve each
1+x<5
subtract 1
x<4
set of answers are 1,2,3

3+x<5
subtract 3
x<2
set of answer is 1
so the possible numbers are
1,2,3
that is 3 numbesr out of 9 so
probability=(total desired outcomes)/(total possible outcomes) so
disred outcomes=3
total possible=9
3/9=1/3
the probabiltiy is 1/3

HELP!! PLEASE A carpenter is framing a window with wood trim where the length of the window is 9 and 1/3 feet. If the width of t
ohaa [14]
We need the perimeter of the window for framing

The window is in the shape of a rectangle with the height of 9 \frac{1}{3} feet and width of 6 \frac{3}{4}. The diagram of the shape is shown below

The perimeter of a shape is obtained by adding up the length of all the sides that form the shape.

The perimeter of the window is 9 \frac{1}{3}+9 \frac{1}{3}+6 \frac{3}{4}+6 \frac{3}{4} = 18 \frac{2}{3}+12 \frac{6}{4} 

We have two whole numbers 18 and 12 and two fractions \frac{2}{3} and \frac{6}{4}

Adding the two fractions that have different denominator 
\frac{2}{3}+ \frac{6}{4} = \frac{8}{12}+ \frac{18}{12}= \frac{26}{12}, which is an improper fraction which we can change into a mixed number 2 \frac{1}{6}

So the perimeter of the window is 
18+12+2 \frac{1}{6} =32 \frac{1}{6} 

and the length of wood needed for the frame is 32 \frac{1}{6} feet
