Hello I know this is random, but thank you for helping me with my questions! It's people like you that make PF such a warm community! :)

I'm a student who works with Mathematica sofware .I'm learning it by myself recently.
I have a question and will appreciate if you help me in this regard.
I have created a 100 rows and 100 columns random matrix which its elements are between 0 to 1(for example it consists of 0.687,...).
Now I want to know how many of these elements are in the range of "0 to 0.5" and how many are in the range of "0.5 to 1".
I also use "Count" function as below but it doesnt answer:
Count[a,{0,0.5}]
("a" is my random matrix).

Please send your answer to my email:
