Checking for possible error in Quant mountain

In this question, should we not be using (0.25)^5 for doing RRRRR calculation?

If not, why do?

Please check and confirm!

1 - (never rains)

What is the probability of (never rains)?

prob of (never rains) is 0.75. I am particularly getting confused with solution of this problem and the one I posted above.

In ex 2 from flashcards we use prob of ALL RAIN and in the mountain we use prob of never rains.

Are those two not different? Or am I missing something in reading/interpreting the questions?

Sorry, my mistake. You’re right, it should be

1 - (rains always)

and indeed there’s an error. We’ll fix this one. Which video/mountain is this from?

Image 1: Quant Mountain (Overwhelmed plan) - Data Analysis 11 AT MOST/LEAST.

Image 2: Group 16 Flashcards!

The Mountain had the error, and that’s fixed.
