  • If you give N users a 5$ coupon, with the probability of usage being P, what is the expected coupon spend? What assumptions would you make to underpin that answer? What is the probability that one of the coupons will be used?
  • Can you explain how the probability of coupon usage and the number of users would impact the overall spend of the coupon?
  • How would you approach calculating the expected spend of a 5$ coupon that was given to N users with a probability of P?
  • What assumptions would you need to make in order to accurately determine the expected coupon spend for N users with a probability of P?
  • If you were given N users a 5$ coupon and the probability of usage was P, how would you calculate the expected spend for the coupon?
  • Could you explain how the probability of coupon usage and the number of users would impact the overall spend of the 5$ coupon?
  • How would you account for the variability in coupon usage when calculating the expected spend for N users with a 5$ coupon?
  • What statistical methods or analysis would you use to determine the expected spend for a 5$ coupon that was given to N users with a probability of P?
  • What additional information would you need in order to accurately calculate the expected spend for N users with a 5$ coupon and a probability of P?
  • How would you approach determining the probability that one of the coupons given to N users with a 5$ value would be used?
  • What factors would impact the expected coupon spend if N users were given a 5$ coupon with a probability of P?
