4. In chess, each player begins the game with two Rooks (R), two Knights (N), two Bishops (B). one Queen (Q), and one King (K). These eight pieces are arranged on a player's starting row in the order R N BQKBNR), pictured here: Fischer Random is a variant of chess in which the eight starting pieces have their locations on the starting row randomized. The only conditions on this randomization are: The King must be placed in between the two Rooks (not necessarily directly adjacent). . The two Bishops must be placed on opposite coloured squares (one light, one dark). Under these conditions, how many possible starting positions are there for a game of Fischer Random chess? Note 1: both players use the same starting configuration, so you only need to count the ossible arrangements for a single player. Note 2: the traditional arrangement of pieces above is also a legal starting position for Fischer Random, so you do not need to exclude it.

Transcribed Image Text:4. In chess, each player begins the game with two Rooks (R), two Knights (N), two Bishops (B).
one Queen (Q), and one King (K). These eight pieces are arranged on a player's starting row
in the order R NBQKBNR), pictured here:
Fischer Random is a variant of chess in which the eight starting pieces have their locations
on the starting row randomized. The only conditions on this randomization are:
• The King must be placed in between the two Rooks (not necessarily directly adjacent).
. The two Bishops must be placed on opposite coloured squares (one light, one dark).
Under these conditions, how many possible starting positions are there for a game of Fischer
Random chess?
Note 1: both players use the same starting configuration, so you only need to count the
possible arrangements for a single player.
Note 2: the traditional arrangement of pieces above is also a legal starting position for Fischer
Random, so you do not need to exclude it.
