Here's how you do it on a 34s:

83 STO J   0,76 STO K
0,15 Norml^–1 => 82,21231062398472

The Prime can solve directly for x with: NORMALD_ICDF(83,0.76,0.15)

In this example, the WP34S used ~16-19 keystrokes depending on PROB menu navigation. The Prime takes ~14 or more depending on having to go to the on-board HELP to guide the syntax to use.
