Observe the median 10 mode 10 mode in sequence. The number of this column is (1 3,38,1/kloc-0, 5 1 1, 512,213,/.

(2)4 (see above)

(3) mode. Because most of the time.

2( 1) As long as the number of white balls accounts for a quarter of the total. I won't elaborate on the method. For example, 1 white 2 red 1 blue

(2) If you don't play basketball, you can't touch it. Half the red and white ball, half the chance. I won't elaborate on the method. For example, 1 red 1 white

(3) Let both sides have equal and fair opportunities. There are many ways to play, and there are two factors to make the game fair. Immediate release laws and regulations. For example, two whites and two reds, who touches the red first.

3 (1) is unfair. Touch two total * * * has the following situation. Mo 12, 13, 14, 15, 16, 23, 24, 25, 26, 34, 35, 36, 45, 46, 56.

(2) a three-person tour. There are many ways to be fair. A simple method, touch a rule 1 or 2, the first person wins, 3 or 4 touches the second person wins, and 5 or 6 touches the third person wins.

4 * * According to the requirements, there are the following situations: 1234, 1243, 1324, 1423, 1432, 2 143, 265433. 3 124, 3 142, 324 1, 32 14, 34 12, 342 1, 4 123, 4 132, 4265438.

The numbers with 1 at the end of (1) are 432 1, 423 1, 324 1, 342 1, 234 1, and six kinds account for a quarter.

(2) It's a little vague: whether the last two digits can only be 12 or 12 or 2 1. The answer is one in twelve. In the second case, the answer is one in six.

(3) a quarter.

None of the three questions can be formulated. With this formula, the computer will: the frequency of a certain situation ÷ the total frequency of occurrence * * *

Alas, it's finally over!
