Ruin probabilities of a discrete-time bi-seasonal model

This bachelor thesis is related with ruin probability of seasonal discrete time risk model. In this case, we choose model of two different claims where one claim happens in odd and another in even time units. According to it, occured claims reduce insurer's surplus. Therefore, we submit recursive formula to calculate ruin probability in bi-seasonal discrete time risk model and its proof. Consequently, theoretical part is illustrated with numerical examples
