In a recent survey, it was found that the median income of families in country A was $57 comma 300. What is the probability that a randomly selected family has an income greater than $57 comma 300 ?

Answer: The probability that a randomly selected family has an income greater than $57 comma 300 = 50% or 0.50.

Step-by-step explanation:

We know that, the median is in general a middle data values in a well ordered data such that

50% of the data values lie below it. 50 % of the of the data values lie above it.

Given : The median income of families in country A was $57,300.

Then, by definition of median, we have

50% of the families have income less than $57,300 ... 50 % of the of the families have income greater than $57,300.

Hence, the probability that a randomly selected family has an income greater than $57 comma 300 = 50% or 0.50.
