The total number of pieces =  9 + 8 + 12 + 6 =   35

 

Of these.....5 are yellow pieces with four holes

 

So.....the probability that the missing piece is a yellow piece with four holes is

 

[ Number of  yellow pieces with four holes ] / [ Total number of pieces ] =

 

5  /   35   =

 

1 / 7
