Answer 1

The answer comes to 1/6 because it produces number 1-6.

Answer 2

One dice possible outcome is (1, 2, 3, 4,5, and 6). The possible outcome is "6" for one dice. The possible outcome for the 2nd dice is also 6. Therefore, the product for the two dice roll is calculated is (6 x 6). This means the highest product for the two dice is 36.

None of the possible calculations will be higher than 36.

Question: What is the probability that the ones digit of this product is 0

possible combinations with product of zero: Dice 1. Dice 2

1st roll 2, 5 (2 x 5 = 10)

2nd roll 5, 2 (5 x 2 = 10)

3rd roll 4, 5 (4 x 5 = 20)

4th roll 5, 4 (5 x 4 = 20)

5th roll 6, 5 (6 x 5 = 30)

6th roll 5, 6 (6 x 5 = 30)

6 combinations out of 36 possible combined outcomes.

6 out of 36

Write ratio as fraction since answer choices are fractions.

ANSWER: 6

36. simplify.

Answer is C.

Answer 3

when two dice are rolled it produces a number between 1 and 6 for one die and another for the other. Normally, we add, but in this problem, you must consider the product. It asks, what is the chance that the product will end with a zero, so the desired outcome must be 10 20 or 30 because the product is limited to 6x6=36 So, one of the die must be 5, 5x2,, 5x4 and 5x6 give us the desired numbers. but 2x5, 4x5 and 6x5 would give the same result with rolled numbers flipped. so there are six rolls which create the desired number out of 36 total different rolls. we setup a fraction (desired outcome)/(total possible outcomes)

6/36 The answer reduces to 1/6

Note how many translations of language have to happen to find the right setup

All math represents a GIVEN, a question, and things which complicate the thinking. Read slowly, and make sense of every sentence before you add more to consider. Students get stuck when they overload on information.
