Hi Don - my answer is #1. Each pilot has a 1/10 chance of drawing the #1 regardless of if they draw first or last. The first pilot has a 1/10 prob of drawing #1. This leaves a 9/10 prob that the first to draw doesn't draw a #1. The second to draw then has a 9/10 x 1/9 prob (equals 1/10) of drawing a #1. Third to draw has a 8/10x1/8 prob (also equals 1/10) of drawing a #1 and so on.
