Each die has 6 possible outcomes (the numbers from 1 to 6).
If we roll two dices, the total number of outcomes is 6 * 6 = 36.
From these outcomes, the ones that have a sum of 4 are:
(1, 3), (2, 2) and (3, 1).
So, if we have 3 wanted outcomes from a total of 36, the probability is:
Therefore the correct option is the second one.
Answer:
240
Step-by-step explanation:
40+30+20=90
360/90 is 4.
So hip hop and rock combined are voted by 60 students.
60 x 4 is 240 students out of a potential 360.
Answer:
x = 18
Step-by-step explanation:
Given
3 + 
= 
Multiply through by the LCM of 2 and 3 to clear the fractions.
The LCM of 2 and 3 is 6, thus
18 + 2x = 3x ( subtract 2x from both sides )
18 = x
Answer: x=30
Step-by-step explanation:
1.Subtract 6 from both sides of the equation
2.Simplify
3.Multiply all terms by the same value to eliminate fraction denominators
4.Simplify
9 is the value of each side. There are 7 sides so 63 divided by 7 is 9.
