A is having dinner in a hotel.

(1) Because customers are required to spend more than 100 yuan to get the opportunity to turn the turntable, customers in A can't get the opportunity to turn the turntable when they spend 98 yuan;

(2) Customer B spends 150 yuan and gets a chance to turn the turntable.

Because the turntable is divided into 16 parts on average,

Six of them are discounted, so P (discount) = 616 = 38;

10% off for 2 copies, p (10% off) = 216 =18;

20% discount for 2 copies, p (20% discount) = 216 =18;

30% off 1 serving, p (30% off) =116;

50% off 1 serving, p (50% off) = 1 16.
