1. a. An ordinary six- sided dice is rolled. Calculate the probability i. of getting a 1 or a 2
ii. of not getting a 1 or a 2
b. What do you notice about your answers in part a?

Part i would be 2/6 or 1/3 (when simplified)

Part ii would be 4/6, or 2/3 (when simplified)

Step-by-step explanation:

There are a total of 6 possibilities you can get on a six sided dice. So for part i, your chances of getting a 1 or a 2 would be 2/6 (2 numbers you want out of 6 choices).

For Part ii, it's 4/6, because there's 4 numbers you have (3,4,5,6) out of 6 choices, that are NOT 1 or 2.

Both answers in Part A can be simplified to a simpler term. The answers in Part A, we can assume, are Equally likely to happen.

Hope this helps!

step-by-step explanation:

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
