Understanding the Problem
- We have 6 boys and 4 girls in a group.
- Exactly one girl and one boy belong to the same parents.
- We need to find the probability that the selected group has no blood relations.
Solution
Total Number of Ways to Select 3 Children
- Total children = 6 boys + 4 girls = 10
- Total ways to select 3 children out of 10 = 10C3 = 120
Number of Ways to Select 3 Children with Blood Relations
- There are 4 ways to choose the boy and girl from the same parents.
- Once we choose the boy and girl, we have 8 remaining children to choose the third child from.
- Number of ways to select 3 children with blood relations = 4 * 8 = 32
Number of Ways to Select 3 Children with No Blood Relations
- Total ways to select 3 children with no blood relations = Total ways - Ways with blood relations
- Number of ways to select 3 children with no blood relations = 120 - 32 = 88
Probability of Selecting Group with No Blood Relations
- Probability = Number of ways to select 3 children with no blood relations / Total number of ways
- Probability = 88 / 120 = 0.7333
Therefore, the probability that the selected group of children have no blood relations is 0.7333.
