Official Explanation
RO1
According to the graph, approximately 12% of the tourists in 1993 stayed on the island for 7 days, and 50% stayed for 14 days. Thus, 12%+50%=62% of the tourists in 1993 stayed on the island for either 7 or 14 days. In 1998, 16% of tourists stayed 7 days and 25% stayed 14 days, for a combined total of 16%+25%=41%. In 2003, 22% of tourists stayed 7 days and 15% stayed 14 days, for a combined total of 22%+15%=37%. Therefore, the percentage of tourists who stayed for either 7 or 14 days is greater in 1993 (62%) than in 1998 (41%) or 2003 (37%), making the probability that a randomly chosen tourist stayed 7 or 14 days greatest in that year.
The correct answer is 1993.
RO2
As explained in the analysis of RO1, 62% of the tourists in 1993 stayed on the island for either 7 or 14 days. Therefore, the combined probability that a randomly chosen tourist that year stayed 7 or 14 days is 0.62, which rounded to the nearest tenth is 0.6.
The correct answer is 0.6.

In 2003, 22% of tourists stayed 7 days and 15% stayed 14 days, for a combined total of 22%+15%=37%. Therefore, the percentage of tourists who stayed for either 7 or 14 days is greater in 1993 (62%) than in 1998 (41%) or 2003 (37%), making the probability that a randomly chosen tourist stayed 7 or 14 days greatest in that year.
The correct answer is 1993.

The largest peak is observed for 14 days in 1993.
Hence, the combined probability is higher for 1993 (First Blank)
And, the cumulated probability is just above 60% (Second Blank)
