3/4 or a 75% chance
Step-by-step explanation:
Out of 4 cards ( 2 3 4 5), here are the cards greater than 3: 4, and 5. That leaves you with a 2/4 chance of drawing one of them. (2 cards, 4 in total).

1/4 + 2/4 = 3/4. Or, a 75% chance.

380/100 = 3.8
so there would be 3.8 action figures per 1%
then 3.8*55 =209
