At least one success in a shop roll
Enter the chance shown in the Daily Shop and how many rolls you might buy. The result is the chance of at least one success if every roll is independent. A September 6, 2026 guide claimed a 1.0% Mythic Jetpack rate. Other fan tables disagree, so replace 1 with the percentage on your screen. This does not know your inventory or guarantee a Jetpack.
Chance of at least one success = 1 − (1 − chance per attempt) raised to the number of attempts.
Default chance is the community-reported 1% Mythic figure, not an official rate. Independent repeats are the model. Pity timers, featured-slot bonuses, and duplicate protection are not included because they are not established.
