This research analysed decisions under risk and ambiguity on a sample of 539 students of the Bratislava University of Economics. Experiments with bets on Ellsberg paradox and familiar events generated results similar to those obtained by Fox and Tversky in 1995. New findings relate to gender differences in decisions under risk and uncertainty. Female students were more ambiguity averse, if they had felt less competent in area of decision. While bets by male participants were significantly higher in financial topics, gender differences were much lower in bets on linguistic topics.
