问题：一个正方形木块，3面为红色，2面为蓝色，1面为绿色。求抛掷这个正方体500次中每一面出现的次数以及每次是哪一面。
书上的一题。不会做，求高人指点。谢谢

用随机函数把
CLS
RANDOMIZE TIMER
DIM A(6), A$(6)
A(1) = 3      '3代表红，4代表蓝，5代表绿
A(2) = 3
A(3) = 3
A(4) = 4
A(5) = 4
A(6) = 5
A$(1) = "RED"
A$(2) = "RED"
A$(3) = "RED"
A$(4) = "BLUE"
A$(5) = "BLUE"
A$(6) = "GREEN"
FOR I = 1 TO 500
   X = INT(RND * 6) + 1
   A(X) = A(X) + 1
   PRINT "NO."; I; A$(X),
NEXT I
PRINT
FOR I = 1 TO 6
   PRINT I; A(I),
NEXT I
END

DIM A(6)
FOR I=1 TO 500
   J=FIX(RND*5)+1
   PRINT J;
   A(J)=A(J)+1
