A whAt the theoretical probability
julsineya [31]

Answer:

a.  \frac{1}{6}

b.  \frac{67}{450}

Step-by-step explanation:

Theoretical probability is what we expect to happen and experimental probability is what actually happens.

a. In theoretical probability, it doesn't matter what happened in the past. So basically we want to know the probability of rolling a 3 when a number cube is rolled.

There are 6 faces (from 1 to 6) in a number cube. And there is 1 "3". So the probabilty of rolling a 3 is:

1/6

b. In experimental probability, we need to know what happened before. When the cube was rolled 450 times, it came up "3", 67 times.

Hence the experimental probabilty of rolling a "3" is:

67/450

0.8 is 10 times as great as what decimal
kondor19780726 [428]
When we say that 2y is 2 times greater than y, this means that if we divide 2y by 2 we will get the y.

Similarly, to know the decimal that is less that 0.8 by 10 times, simply divide 0.8 by 10 as follows:
decimal = 0.8 / 10 = 0.08

This means that 0.8 is 10 times larger than 0.08
