Probability of No Rain

[mathdad]

There is an x probability of rain tomorrow. What is the probability of no rain tomorrow?

Let me see if I get this.

P(no rain tomorrow) = (1 - x).

Yes?

Agree.

 

[mathdad]

Agree.

Thank you. I wasn't too sure at first. So, in my mind, I replaced x with a certain percent and subtracted that percent from 1.

Percents range from 0 to 100.

Percents range from 0 to 100.

Correct. In terms of probability, we can also say between 0 and 1.

please tell us what is your 'planned' path-forward?

My plan is to revisit math courses that I took back in the 1980s and 1990s. I miss school, particularly math classes. Now as a middle-aged man, there's nothing better than solving math problems to keep my memory and brain cells alive and well. No pun intended.

your 'planned' path-forward

I was interested in knowing (planned path-forward) to solve THIS problem. What is the answer that you calculated.

It has been solved. Here, x represents a certain percent chance of rain tomorrow. The problem is asking for an equation. I will let r = no rain tomorrow.

I get this:

P(r) = (1 - x).
