As a matter of interest, why =COUNTIF(A1:A10,"6") and not
=COUNTIF(A1:A10,"=7") ?

The answers would, of course, be the same if all the numbers are integers,
but the OP didn't say that they were integer, and we wouldn't want to
confuse him.

All your questions can be answered using the same technique. For example,
if
we have data in A1 thru A1000 and pick a sample at random:

=COUNTIF(A1:A10,"6")/1000

is the probability the value is greater than or equal to 7. Same approach
for the other cases.

I have 4 questions that require me to use and show Excel functions
(formulas)
in my worksheet. I can not seem to find the correct way to input
formulas
for the probability of the following information:

I need to find the probability of a number greather to or equal to 7
I need to find the probability of numbers less than or equal to 50K
I need to find the probability of numbers between 150K and 250K
I need to find the probability of numbers less than 49K

I have empirical data sets for to use to find all of the above
information
but can't seem to find the proper formulas. CAN ANYONE OUT THERE HELP.
