This got me thinking about how the chits are spread and the odds of
drawing a particular valid chit. Note that Green and Yellow have the
exact same number and distribution of chits.

This is for the drawing of 1 chit. If someone wants to extend these
tables to take into account drawing multiple chits, please do so.

Number of Chits:
      G/Y     Red     G&Y     G/Y&R   All
T:    20      50      40      70      90  (110 including special)
0:     3       5       6       8      11
1:    10      20      20      30      40
2:     7      15      14      22      29
3:     5      10      10      15      20
Boom: 5
Firer: 2
Targeting: 5
Mobility: 7

Odds of drawing a specific chit:
 %    G/Y     Red     G&Y     G/Y&R   All
T:    18.2    45.5    36.4    63.6    81.8
0:    02.7    02.7    05.5    07.3    10.0
1:    09.0    18.2    18.2    27.3    36.4
2:    06.4    13.6    12.7    20.0    31.8
3:    04.5    09.0    09.0    13.6    18.2
Boom: 04.5%
Firer: 01.8%
Targeting: 04.5%
Mobility: 06.4%
