Tbh this is free points, and I just want to chat aos, but i do need helo with probability, can someone help me understanf how to work with probability

So probability is the likelihood of something occurring. like getting heads or tails. There is 1 heads and 1 tails.

So your sample space is heads or tails and that is your total amount of outcomes. So to be realistic you have 1/2 chance of flipping a heads or tails. There is 1 heads and 1 tails over the total amount of outcomes.

of course as you continue into probability there is different formulas for "and" and "or" questions and questions that ask you for the probably of a given b

P(A|B) and P(B|A)

then we continue on and there is determining whether something is dependent or independent

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
