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

Explanation:
This is the simplest way to write it using Python.
After you use the create sequence statement to create a sequence, you can use the NEXTVAL pseudo column to get the next value in the sequence.
<h3 /><h3>How do you create a sequence?</h3>
- You must have the Create any sequence system privilege to create a sequence in another user's schema.
- Specify the schema that will hold the sequence.
- If you leave out schema, Oracle Database will create the sequence in your own schema. Name the sequence that will be created.
- Pseudo-columns allow selection, but you cannot edit, update, or remove their values.
- A pseudo-column is analogous to a function that does not accept any inputs. This section goes over the two pseudo-columns, CURRVAL and NEXTVAL.
- A pseudo column is a "column" that displays a value when a value is selected but is not one of the table's true columns.
- Two examples are SysDate and RowID. It is frequently used in tandem with the DUAL table.
- After you utilize the make sequence statement to make a sequence, you can utilize the NEXTVAL pseudo column to obtain the next value in the sequence.
