How to draw a paper lottery ticket for five people?

The probability of the first person winning the lottery is: 2/5=0.4. The second person draws a lottery ticket in the following situations: 1, and the first person draws a lottery ticket. At this time, the probability of the second person winning the lottery is 1/4, so it is 0.4 ×1/4 = 0.12. So the probability is 0.6*2/4=0.3, so the probability of the second person winning the lottery is 0. 1+0.3 = 0.4. There are several situations when the third person draws a lottery ticket: 1, the first person draws a lottery ticket, and the second person also draws a lottery ticket, so the probability of the third person drawing a lottery ticket is 0.2, and the first person draws a lottery ticket. Then the probability of the third person winning the lottery is: 0.4 * 0.75 *1/3 = 0.1.3; If the first person fails to win the lottery, the second person wins the lottery, and the probability of the third person winning the lottery is: 0.6 * 0.5 * 1/3 = 0.655. Then the probability of the third person winning the lottery is 0.6*0.5*2/3=0.2, and the probability of the second person winning the lottery is 0. 1+0. 1+0.2 = 0.4. Also analyze the probability of the fourth person and the fifth person. So equal. :)
