Rolling a single die student gets the row
1 5 3 2 3 6 5 6 3 3 4 4 1 3 6 5 3 2 2 6,
where numbers
- 1, 5, 3, 3, 5, 3, 3, 1, 3, 5, 3 are odd;
- 2, 6, 6, 4, 4, 6, 2, 2, 6 are even.
Here are 10 odd numbers and 10 even numbers. Then the experimental probability of rolling an even number is
Now count the theoretical probability of rolling an even number. A die has 6 numbers: 1, 2, 3, 4, 5, 6. Three of them are even and three of them are odd. Then the theoretical probabilty is
Answer: both probabilities are the same
