La diferencia promedio entre el precio en cada tienda y la media es de $ 3
La media de un grupo de datos es el valor promedio de ese grupo de datos.
Mientras que la desviación media nos dice en promedio cuánto se desvían estos valores de la media (que es el medio).
Dado que la media es de $ 45, el precio promedio del cuaderno de bocetos es de $ 45. Además, dado que la desviación media es de $ 3, la diferencia promedio entre el precio en cada tienda y la media es de $ 3.

Answer:
- <em>The probability that the second favorite character will die given that the first favorite character dies is</em><u> 0.53</u>
- <u>This kind of probability is called conditional probability</u>
Explanation:
Name the events and their probabiities:
- Event A: her favorite character will survive, so P (A) = 0.70
- Event B: her her second favorite character will die, so P(B) = 0.75
- Both characters will die ⇒ P (B and not A) = 0.16
You want to find P (B | not A).
That is the probability of the succes B (the second favorite character will die) given other event (not A or the first favorite character dies) is certain (it happens) and that is called conditional probability.
- P (not A) is the complement probability of A, so P (not A) = 1 - P(A) = 1 - 0.7 = 0.3
So, you have P(B), P(not A) and want to find P (B | not A)
The definition of conditional probability is:
- P (X | Y) = P (X and Y) / P (Y)
So, replacing with our terms, we get:
- P ( B | not A) = P (B and not A) / P (not A) = 0.16 / 0.3 ≈ 0.53
The answer would be x=4 and y=-2.
