If you roll two number cubes, what is the probability of their sum being 9 or higher?
aalyn [17]

Answer:

Pe = \frac{10}{36}

Step-by-step explanation:

Well, a standard cube number (dice) has numbers from 1 to 6. So the combinations that give 9 or higher, are 3-6, 6-3, 4-5, 5-4, 4-6, 6-4,5-6, 6-5, 5-5, 6-6. We will call this favorable cases (Fc) = 10

Yet, the total number of cases (T) is 6 different number by 6 different combinations (1-1 , 1-2 , 1-3 ..... 6-6), 6 x 6= 36 = T.

So, in order to calculate the probability of an event (10/36), you can use the following formula:

Pe = \frac{Fc}{T}

Pe = \frac{10}{36} = 0.2777

Factor each trinomial completely.<br> 4x^2 - 25b^2 and x^2 - 81
GenaCL600 [577]

Step-by-step explanation:

4x2 - 25b2

We can solve it by the squares so

(2x - 5b) (2x + 5b)

2) x2 - 81

The same case is here so

(x - 9) (x + 9)

<em>x=-2</em>

15x+10y=20
15*(-2)+10y=20
