What is the probability that child chosen random scored 3mark.
I would need more information to answer this question properly.
- How many marks are possible for the child to score?
- How many children are we selecting from?
- Do all children have an equal chance of scoring 3 marks?
Once you provide me with this information, I can give you the probability that a child chosen at random will score 3 marks.
To determine the probability that a child chosen at random scored 3 marks, we need to know the total number of children and the number of children who scored 3 marks.
Let's say there are 100 children in total, and 20 of them scored 3 marks.
The probability can be calculated by dividing the number of children who scored 3 marks by the total number of children:
Probability = Number of children who scored 3 marks / Total number of children
In this case, the probability would be:
Probability = 20 / 100 = 0.2
So, the probability that a child chosen at random scored 3 marks is 0.2 or 20%.
To find the probability that a child chosen at random has scored 3 marks, we need two pieces of information: the total number of children and the number of children who scored 3 marks.
Let's say we have a total of N children and K of them scored 3 marks.
The probability can be calculated using the formula:
Probability = Number of favorable outcomes / Total number of outcomes
In this case, the number of favorable outcomes is K (the children who scored 3 marks) and the total number of outcomes is N (the total number of children).
So, the probability that a child chosen at random scored 3 marks is K/N.
