Answer 2

how do i solve this?

Answer 3

Omg no more probabilities I can't believe I have completed that module lol. Good luck it is really awful

Answer 4

lmao

Answer 5

i hate every moment of it tbh

Answer 6

GeoGebra and Desmos solve this kind of problems try them

Answer 7

yeah i can use that but like it prolly wont give me an actual explanation

Answer 8

and i dont wanna rely on that solely

Answer 9

That's terrific.. Good luck and here's my best buddy he might help
@Mathmale if he was online anyway

Answer 10

:)

Answer 11

You need to first define a probability distribution such that the total area is 1.
We are given P(x) = k , for all x between 1 and 3.

Answer 12

ok

Answer 13

One of the axioms is. $$ \int_{-\infty }^{\infty} f(x) = 1 $$In our problem P(x) = k
$$
\int_{-\infty }^{\infty} k = \int_{1 }^{4} k = 1
$$Solve for k.

Answer 14

um i've never seen that symbol before

Answer 15

The area of that rectangle must equal to 1 by the probability axiom. The height of the rectangle is some value k. The base is 3. The area is therefore 3*k.

Answer 16

but like its asking for a value
