Mathematical arrangement and combination of probability numbers
Answer: Because there are enough balls, the probability of taking out the red ball every time is110 = 0.1;

1, and the probability of red ball appearing twice is p = 0.1x 0.1= 0.01;

2. The probability of taking out the red ball three times p = 0.1x 0.1x 0.1= 0.001;

3. The probability of taking out the red ball four times p = 0.1x 0.1x 0.1x 0.1= 0.0001;

4. The probability of taking out the red ball five times p = 0.1x 0.1x 0.1x 0.1= 0.00001;
