can you please help me with this using R:

The probabilities that are calculated with pnorm() are sometimes very small; for precision-related reasons, it might be better to store those probabilities on the log scale. Give two ways that from this answer:

qnorm(0.3)

[1] -0.5244005

> round(qnorm(0.3),4)

[1] -0.5244

how it could be stored on the log scale. One of them must only use prnorm); the other one can use pnorm) and another function.
