• Answer:

  if they make 6 calls an hour, they make 12 calls in 2 hours they have a .3 probability of making a sale they have a .7 probability of not making a sale 12C4 * .3^4 * .7^8 = 0.231139696095 P(x = 4) = 23.11% .7^12 = 0.013841287201 P(x = 0) = 1.38% 12C2 * .3^2 * .7^10 = 0.167790297906 P(x = 2) = 16.78%
