Answer:
B is epic answer
Step-by-step explanation:
Answer:
a. P(X=50)= 0.36
b. P(X≤75) = 0.9
c. P(X>50)= 0.48
d. P(X<100) = 0.9
Step-by-step explanation:
The given data is
x 25 50 75 100 Total
P(x) 0.16 0.36 0.38 0.10 1.00
Where X is the variable and P(X) = probabililty of that variable.
From the above
a. P(X=50)= 0.36
We add the probabilities of the variable below and equal to 75
b. P(X≤75) = 0.16+ 0.36+ 0.38= 0.9
We find the probability of the variable greater than 50 and add it.
c. P(X>50)= 0.38+0.10= 0.48
It can be calculated in two ways. One is to subtract the probability of 100 from total probability of 1. And the other is to add the probabilities of all the variables less than 100 . Both would give the same answer.
d. P(X<100)= 1- P(X=100)= 1-0.1= 0.9
De ahí que la fracción de la mantequilla total que corresponde a cada postre sea 1/4
Si con 16 barras de mantequilla se prepararon 20 postres, esto se puede expresar como:
16 pegatinas = 20 postres
Para obtener la fracción del total de mantequilla que corresponde a cada postre, podemos escribir;
x = 1 postre
Divide ambas expresiones
16 / x = 20/1
20 veces = 16 * 1
20x = 16
x = 16/20
x = 4/5
De ahí que la fracción de la mantequilla total que corresponde a cada postre sea 1/4
