You roll a number cube. what are the odds that you will roll an even number?

50% or 1/2

Step-by-step explanation: Probability is the likelihood that an event will happen. We can find the probability of an event using the ratio shown.

In this problem, we want the probability of rolling an even number or P (4). This means that the even numbers which are 2, 4, and 6 are favorable outcomes.

Since there are 3 even numbers on the dice, there are 3 favorable outcomes. It's equally possible to roll an even number as it is to roll an odd number because there are the same amount of even numbers and off numbers on the dice.

Therefore, the probability of rolling an even number is 50%

no not all of them.

step-by-step explanation:

some of them have a square base.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
