There were 30 people. 9 visited the museum and zoo. 14 visited the zoo but not the museum, 5 visited the museum and not the zoo and 2 visited the zoo but not the museum. What is the probability that a person picked at random visited the museum and not the zoo?
Are you sure that probability is a geometry subject?
It's probabliity
question above is probability
You said:
14 visited the zoo but not the museum, ...
2 visited the zoo but not the museum.
So, which is it?
in order tn study the motion of body is very useful to par the distance time taken and the motion and draw the coter ponding distance two group
To find the probability that a person picked at random visited the museum and not the zoo, we need to calculate the number of people who visited the museum only and divide it by the total number of people.
We can break down the information given:
- 9 people visited both the museum and the zoo.
- 14 people visited the zoo only.
- 5 people visited the museum only.
- 2 people visited the zoo but not the museum.
To calculate the number of people who visited the museum only, we can subtract the number of people who visited both the museum and the zoo (9) and the number of people who visited the museum but also visited the zoo (5).
So, the number of people who visited the museum only is 5 (total museum visitors) - 9 (people who visited both) = -4.
However, it is not possible to have a negative number of people, so we assume that there was an error in the information provided.
Hence, we cannot calculate the probability of a person visiting the museum and not the zoo with the given information.
