During the Spring Festival, shopping malls launched the activity of "throwing golden eggs to send red envelopes". Anyone who buys more than 1000 yuan at a time can get the opportunity to throw two golden eggs at a time. such as

Solution: (1) According to the requirement of "only the golden eggs at the bottom of each string are allowed to be smashed at a time",

All possible outcomes of the customer's golden eggs are:

A 1B 1，A 1B3，A 1A3，B3A2，B3A3，

Because only egg B has a red envelope hidden in it,

So the probability that A can get a red envelope: P A =? 4/5;

(2) If A breaks A 1B 1, the possible results of B breaking eggs are: B2B3, B2A3, B3A2, B3A3,

If A smashed A 1B3, the possible results of B smashing eggs are: B 1B2, B 1A2, B 1A3, A2A3,

If A smashed A 1A3, the possible results of B smashing eggs are: B 1B2, B 1B3, B3A2,

If A smashed B3A2, the possible results of B smashing eggs are: A 1B 1, A 1A3,

If A smashed B3A3, the possible results of B smashing eggs are: A 1B 1, A 1A2,

So, the probability of customer B getting two red envelopes: P B =? 4/ 15.

So the answer is:

( 1)A 1B 1，A 1B3，A 1A3，B3A2，B3A3？ 4/5;

(2)? 4/ 15.
