Responder:
Pantalón = 50 €
Zapatos = 76 €
Explicación paso a paso:
Total pagado por pantalón y zapatos = 126
Sea el precio del pantalón = p; zapatos = s
p + s = 126
1,14 p = 0,75 s
p = 0,75 s / 1,14
0,75 s / 1,14 + s = 126
(0,75 s + 1,14 s) / 1,14 = 126
0,75 s + 1,14 s = 143,64
1,89 s = 143,64
s = 143,64 / 1,89
s = 76
p + s = 126
P = 126 - s
P = 126 - 76
p = 50
Answer:
Step-by-step explanation:
We have been given that three cubes are being rolled and we are required to find the probability of getting 4 on each of the three cubes.
We know the probability of rolling a 4 on one cube will be 
. Since there are 3 cubes, the probability of rolling 4 in each of the individual cubes will be .
But we want 4 to be rolled on all three cubes at once, in order for that to happen, we need to get a four on first cube AND second cube AND third cube. Since there is AND between the events, we will multiplied their probabilities as per counting principle. Thus, the required probability of rolling 4 on each of the three cubes is 
which simplifies to .
The answer is A becuase to find the mean you need to first add all the numbers provided in this case 5 then you divide the total by 5
