6 members have to be selected from different field.10 from java,5 from Microsoft,8 from oracle,2 from IBM. What is the possible combination?
Answers
Answer:
1,68,000
Step-by-step explanation:
In the question it is mentioned as, it has to be selected from different fields
so, consider out of 6 positions, 4 position is taken up by each person in each field.
ie., 10C1 * 5C1 * 8C1* 2C1
then we know that there are 2 places remaining. It is taken up from (25-4) members. (ps: 25 is total members and 4 is already selected members)
so it goes like, 10C1 * 5C1 * 8C1* 2C1* 21C2 = 1,68,000
Answer:
The correct answer of this question is the 1,68,000 .
Step-by-step explanation:
Given - 6 members have to be selected from different field and 10 from java, 5 from Microsoft, 8 from oracle, 2 from IBM.
To Find - Write the possible combination .
There are two spots left, which are filled by (25-4) members. and there are a total of 25 members, with four already chosen.
It works out to 10C1 * 5C1 * 8C1* 2C1* 21C2 = 1,68,000
1,68,000 is the possible combination .
The product of the total possibility for each of the things determines the overall number of possible combinations for a set of elements. A combination is a mathematical technique for calculating the number of potential arrangements in a set of things where the order of the items is irrelevant.
