Solution

Out of a total of 16, who have entered the draw, there are 6 residents of Gaston. The probabilty P₁ of selecting a resident of Gaston is 6/16. Now, 15 customers remain in the draw, out of which 5 are from Gaston. The probabilty P₂ of selecting a resident of Gaston is 5/15.Thus the probabilty that both the customers selected are Gaston residents is P₁*P₂ = (6/16)*(5/15) = 1/8
