You randomly choose one chess piece. without replacing the first piece you choose a second piece. find the probability of choosing the first piece and then the second piece.8. bishop and bishop

Total of 16 pieces in the chess which foam our sample space.
Total of 2 pieces of bishop.
If you first chose the bishop then probability =2/16=1/8=0.125
If you again chose the bishop without replacement(total sample space left=15 and 1 piece of bishop left) then probability =1/15=0.0666

Where is the scatter plot
