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

How do you solve<br> -2=u-93÷-3
viktelen [127]

Answer:

u=91

Step-by-step explanation:

-2=u-93÷-3

multiply both sides by 3

3(-2)=(u)3+(-93÷-3)3

-6=3u-279

add 279 to both sides

-6=3u-279

+279. +279

273=3u

divide by 3

273÷3=3u÷3

91=u
