(1) The basic method of classical probability in senior high school is to write all the basic events, calculate the number of all the basic events and the number of basic events satisfying event A, and then calculate the ratio to be probability. * * * There are basic events:12x12; Let's call "the two colors obtained are the same" event A, and the basic event satisfying event A is: 8x6+4x6=72, so P(A)= 1/2.

(2) Simply consider the opposite event, that is, the probability of not sprouting is 0.2 5, then the probability of sprouting at least once is 1-0.2 5.
