The last two options are correct, but it looks like you’ve got them :)
I believe it would be 18u/2n or maybe 2n:18u or 18u:2n
Hope this helped

Answer:
Step-by-step explanation:
Given that an ordinary deck of 52 cards is shuffled and the cards are then turned over one at a time until the first ace appears.
the first ace is the 20th card to appear
This implies that there are still 32 cards with 3 aces in it.
But 2 clubs can be either 1 remaining or nothing remaining
a) ace of spades
3 aces out of 32
Prob =
b) 2 of clubs
P (2 club already gone in first 19 cards) +P(2 club is in the remaining)
= 0+P(first 20 cards not 2 clubs )*P(2 club in 21st draw)
=
Set up a proportion
90/x = 60/100
60x = 9000
x = 150
if you're wondering why I used 60 instead of 40 in the proportion it is because $90 is 60% of the original price, not 40%
hope this helps!
