Your answer is wrong. You only listed four situations, but you didn't calculate the probabilities of the four situations separately. This is a puzzling idea. It can be understood that the probability of all males is1/2 *1/2 *1/2 = 1/8, the probability of all females is also1/8, and the probability of two females and two males is equal, which is 3/8. Of course, your teacher's solution is clear. . This kind of problem will be easy to handle when you learn the algorithm of probability in the future. Do a formula to solve it.

The mistake you solved is "the results of two males have nothing to do with the arrangement order of eggs, so they belong to the same class!" " Although the result of this sentence has nothing to do with the order of eggs, the probability is different. 1 No.2 is male and female, 1 No.2 and No.3 are male and female, and 1 No. The probability of these three cases is 1/8. So the total probability is 3/8.
