A number cube is labeled 1 through 6. What is the probability of NOT<br> rolling a 2?
Andre45 [30]

Answer:

Step-by-step explanation:

each of the 6 number has a 1/6 chance of being rolled

 1       2       3      4      5       6

1/6     1/6    1/6    1/6    1/6    1/6

Every time the cube is rolled  there is a 6/6 chance of any number comes up

1/6  +   1/6  +  1/6 +   1/6 +   1/6  +  1/6   = 6/6     or  1  

What is the probability of NOT rolling a 2? Any other number

 1        2       3        4        5         6

1/6  +   0  +  1/6 +   1/6  +  1/6 +   1/6   =   5/6    or    0.8333
