It's essentially a binomial distribution, the probability of getting a certain amount of succes in a number of attempts.

https://en.wikipedia.org/wiki/Binomial_distribution

Probability of a succes is 10%

k = the amount of succesful attempts

r = The amount of players during the mission with a radiant relic

>= : Greater or equal

1-(P(0; n; 0.1))^r >=0.99

Change the value of n till the condition is fulfilled.
