Answer:

children = 177, adults =215

Step-by-step explanation:

im too lazy to write but solve this with a systeme

x(children),y(adults)

x+y=392

x=392-y

2.5y+1.25x=758.75

2.5y+1.25(392-y)=758.75

2.5y+490-1.25y=758.75

490+1.25y=758.75

1.25y=758.75-490

1.25y=268.75

y=268.75/1.25

y=215

x=392-215=177(number of kids)

You are going to roll two dice. Let the variable x = the sum of the numbers rolled. What is the probability that x = 9 ?
Vladimir79 [104]

The  first cube can land in any one of  6  ways.
The  second cube can land in any one of  6  ways.
Total number of ways that  2 dice can land = (6 x 6) = 36 ways.

For any of these ways, the sum of the numbers rolled is  9 :

3, 6
4, 5
5, 4
6, 3

There are  4  ways to roll a 9, out of a total of  36  ways that
the dice can land.  So the probability of rolling a  9  is

       4 / 36  =  1 / 9  =  <em>11-1/9 percent</em>
