Does anyone know Experimental Probability?

1 answer:

7 0

If you roll a fair 6-sided die you can get 1, 2, 3, 4, 5 or 6. In total there are 6 possibilities for the outcomes. The theoretical probability to roll each number of 6 possible is the same and equal to 1/6.

If you roll a fair 6-sided die 600 times, you can expect that near 1/6 of these attempts will get you 3's. Then you expect about 600·1/6=100 3’s (you can't suppose to get exactly 100 3's, because the experimental probability may differ from theoretical).

Answer: correct choice is A.

There are 4 red marbles, 5 green marbles, 6 yellow marbles and 3 blue marbles in a bag. You select one marble at random. What is

steposvetlana [31]

Answer:

The probability can be written as;

6/18

0.333

33.3%

Step-by-step explanation:

First we find the total number of marbles.

4 + 5 + 6 + 3 = 18

Now write the probability in the form of (favourable outcomes / possible outcomes), or 6/18.

Now let's divide.

6 ÷ 18 = 0.33333333... repeating decimal

0.333 × 100 = 33.33333.....%

We can also round this to 33%
