Two numbers rolled can be added to get a sum. Find P(sum is even.)

Mathematics

When you roll two numbers you have four kinds of outcomes: EE, EO, OE, OO (where E = even, O = odd).

You get an even sum only if you sum two numbers that are both even or both odd, therefore the outcomes wanted are two: EE and OO.

Therefore:
P(sum is even) = 2 / 4 = 0.5

Hence, there is a 50% probability that, when you roll two numbers, their sum will be even.

<h3>Answer:</h3>

28inch^2

<h3>Step-by-step solution:</h3>

Rectangle:

<em>[</em><em>L</em><em>e</em><em>n</em><em>g</em><em>t</em><em>h</em><em> </em><em>x</em><em> </em><em>B</em><em>r</em><em>e</em><em>a</em><em>d</em><em>t</em><em>h</em><em>]</em>

5 + 3 = 8inch

8 x 2.5 = 20inch^2

Right Triangle:

<em>[</em><em>1</em><em>/</em><em>2</em><em> </em><em>x</em><em> </em><em>B</em><em>a</em><em>s</em><em>e</em><em> </em><em>x</em><em> </em><em>H</em><em>e</em><em>i</em><em>g</em><em>h</em><em>t</em><em>]</em>

1/2 x 5 x 2 = 1/2 x 10

= 5inch^2

Left Triangle:

<em>[</em><em>1</em><em>/</em><em>2</em><em> </em><em>x</em><em> </em><em>B</em><em>a</em><em>s</em><em>e</em><em> </em><em>x</em><em> </em><em>H</em><em>e</em><em>i</em><em>g</em><em>h</em><em>t</em><em>]</em>

1/2 x 3 x 2 = 1/2 x 6

= 3inch^2
