Afair dice is rolled. work out the probability of getting a factor of 12. give your answer in its simplest form.

The probability of getting a factor of 12 on a fair dice is 5/6 or approximately 83%.

Step-by-step explanation:

Probability is expressed as a fraction where the denominator is the total number of outcomes and the numerator is the number of desired outcomes.  In this case, the desired outcome is any factor of 12.  The factors of 12 are the numbers we multiply together to get that number:  1, 2, 3, 4, 6 and 12.  Since a fair dice has the total outcomes of either 1, 2, 3, 4, 5 or 6, then the total outcomes is 6 and the possibility that we could roll the desired outcome (factor of 12) is 5, the probability is 5 out of 6 or 5/6, which when divided is approximately 83%.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
