Answer: 0.1937
Explanation:
Given : A bowl contains 20 candies; 15 are chocolate and 5 are vanilla.
If we select 5 candies, then the number of ways to select them is given by permutations.
The number of ways to select 5 candies is given by :-
The number of ways of selecting any 5 candies out of 20:-
Now, the probability that all 5 are chocolate :-
Hence, the probability that all 5 are chocolate =0.1937
The answer to your question is b
Answer:
The computer can do 12000 searches per second. Suppose there are 60000 inventory items. And we need to search one item from it in a sequential manner. The computer can do 12000 searches in one second. Hence it can search in a list of 60000 inventory in 5 seconds, as 12000 x 5 =60000 searches, in the worst case. And if the item is below 12000 on the list, it will take less than 1 second(1/12000 sec in best case), and so on.
And if we assume that the list is sorted, and perform a binary search. then in the worst case, the number of searches required in the worst case will be 60000/2= 30000. And the time required will be 30000/12000= 5/2=2.5 seconds, and (1/24000) seconds in the best case. Its 1/24000 as its binary search.
