Party A, Party B and Party D attended the meeting through election. In order to be fair, they decided to adopt the method of "drawing lots". Is the last person as likely as the first person? How much is each?
Answer: Similarly, no matter which lottery ticket it is, the probability is 1/4.
This can be solved. If you don't understand, please ask.
The first one: p =1/4;
Second: p = 3/4x1/3 =1/4;
The third one: p = 3/4x2/3x1/2 =1/4;
The fourth one: p = 3/4x2/3x1/2x11=1/4.
