What is the minimum number of games that the gambler must play so that the probability of winning is greater than 9%?*

judging by the marks that it would be allocated (only 2) i assume it must be fairly simple and im simply missing the simplicity... that or it is much harder. i suspected that it may be a binomial probability question but still got no where.

how can i go about solving this problem?
