Answer:
The number of drops that the official tester will need for two eggs in the worst case scenario = 2
Step-by-step explanation:
Since the ad is to prove the hardness of tje eggs and high ratings correspond to the Ostrich eggs not breaking till the topmost floors, the worst case scenario will be that the Flightless Ostrich Farm's eggs are of the lowest ratings and will break on the first attempt from the first floor.
If he takes two eggs, the worst case scenario is that the two eggs each break on their first trials; that is, from the first floor.
So, the number of drops that the official tester will need for two eggs in the worst case scenario = 2
One drop for the first egg from the first floor, it breaks, then the second drop for the second egg from the first floor too and it also breaks.
Hope this Helps!!!
