Suppose the butterfly is 1, 2, 3. Then it is possible that 1, 2, 2, 3 and 1, 3 may fall on the same flower.

Then there are three more flowers, so there are nine possibilities.

It can be calculated by probability in mathematics.

The calculation of extended data probability is determined according to the actual situation, and there is no unified general formula. The key to solving the probability problem lies in the concrete analysis of specific problems. Then, consider using an appropriate formula.

But there is a common formula:

P(A)=m/n

"(a)" indicates an event.

"m" indicates the total number of events (a)

"n" is the total number of total events.
