Iroll the dice 20 times. what is the probability of rolling a one or two?

1/3 is the answer or 2/6

The answer is 1:30 or 1/30.

There are 6 possible outcomes from rolling a dice, so you multiply 6 and the amount of times rolled, in this case its 20.

6 x 20 = 120

It says what is the probability of rolling 1 or 2 from the 20 rolls. So you multiply 2 and 20, which gives you 40. 

The probability is 40/120, but you must simplify it, by dividing both sides of the fraction by its greatest common factor. The GCF is 40, so it is 1/30

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
