In a board game, you must roll two 6-sided number cubes. You can only start the game if you roll a 3 on at least one of the numb
Maru [420]

A) You can have

1-1; 1-2; 1-3; 1-4; 1-5; 1-6; 2-2; 2-3; 2-4; 2-5; 2-6; 3-3; 3-4; 3-5; 3-6; 4-4; 4-5; 4-6; 5-5; 5-6; 6-6

Those are all possible outcomes

B) Only 6 of the options include at least one three

The fraction is: 6/21 or simplified 2/7

C) To find this answer we need a percentage

to find that...

6/21 and ?/100

(When writing put it as a fraction to visually see the next part)

We will cross-multiply: the ? will be represented by x

(6 times 100) + (21x)

600 = 21x

Now divide 600 by 21 to get about 28.6

Since 28.6 < 34 then we would get a probability of less than 34 out of 100
