Hi all
Chapter-7, page5
Can someone please explain why it is written that qx and tqx are the rates of mortality ?
As far as I know, these are the probabilities, not rates! Anyone please help me to understand - What's the difference between a probability and a rate and whether tqx is a rate or a probability?

Thanks in advace.

You might want to refer to this:

It seems that the two words are sometimes used synonymously.

Hope this helps!
