Answer:
The probability is 0.8
Step-by-step explanation:
- if u see the table clearly, there are 30 houses in total with 2 bathrooms.
- by the general definition of probability,
probability of an event P =
- so, here 30 will be the denominator in the above formula(by definition).
- from the table, in the 3rd column and 2nd row (desirable box) i.e, the one which represents 2 bathrooms and 3 bedrooms, has the entry as 24.
- so, the numerator for above given formula will now become 24.
therefore probability P=
- So, the probability is 0.8.
