我认为应该是选A (即Jack从容器A中取出一个红的). 答案如下

A (2 red 8 white) B (3 red 10 white)

1) J gets 1 red from A, leaving 1 red and 8 white, total of 9 left in A
Garry gets red from A Garry gets red from B
M gets 1 red from A 0/8 < 3/13
M gets 1 white from A 1/8 < 3/13
M gets 1 red from B 1/9 < 2/12
M gets 1 white from B 1/9 < 3/12

2) M gets 1 red from B, leaving 2 red and 10 white, total of 12 left in B
Garry gets red from A Garry gets red from B
J gets 1 red from A 1/9 < 2/12
J gets 1 white from A 2/9 > 2/12
J gets 1 red from B 2/10 > 1/11
J gets 1 white from B 2/10 > 2/11
