Answer:
98 boxes
Step-by-step explanation:
If 56 is 
of the total, we can set up an equation like this:
Where T is the total number of boxes.
Solving for T gives us the answer:
There were 98 boxes in total.
Let's compute the two factors separately: as for "the sum of -13/5 and 12/7", we have to rewrite the two fractions so that they have the same denominator. Since the least common multiple of 5 and 7 is 35, we will change both fractions so that they have denominator 35:
So now we can sum them:
Multiplication is easier, since you just have to multiply numerators and denominators with each others:
Finally, we must divide the two fractions. Dividing by a fraction is the same this as multiplying by the inverse of that fraction, i.e. we have to switch numerator and denominator:
Answer:
P = 15/36 = 0.4166...
Step-by-step explanation:
Cada dado tiene 6 caras, con los números entre 1 y 6.
Entonces tenemos dos eventos, con 6 posibles resultados cada uno.
El número total de resultados para el evento de lanzar los dos dados, es el producto de los números de resultados para cada dado, entonces tenemos:
C = 6*6 = 36 posibles resultados.
Ahora tenemos que contar el número de resultados en donde la suma es menor a 7.
Usando la notación:
(resultado del dado 1) y (resultado del dado 2) = suma
Esos son:
1 y 1 = 2
1 y 2 = 3
1 y 3 = 4
1 y 4 = 5
1 y 5 = 6
2 y 1 = 3
2 y 2 = 4
2 y 3 = 5
2 y 4 = 6
3 y 1 = 4
3 y 2 = 5
3 y 3 = 6
4 y 1 = 5
4 y 2 = 6
5 y 1 = 6
Hay 15 resultados donde la suma de los resultados individuales es menor a 7.
Entonces de un total de 36 posibles resultados, 15 cumplen lo que queremos, asi que la probabilidad de que las caras hacía arriba sumen un número menor que 7 son de 15 entre 36, o:
P = 15/36 = 0.4166...
