You are really a life saver man, i really appreciate you, you helped me so much because my final exam is tomorrow and i never felt more ready for a physics exam, i never understood anything from the teacher that teaches my class and i always failed so wish me luck in my final.

So the example questionbon corrected count rate, were you not supposed to consider the fact that they gave you the half life in hours but the count rate in seconds?
