1)1993, Since per the graph there is a peak for 14 days in year 1993 and peak for 7 days in 2003, but if we see the cumulative results,then the highest peak in 1993 for 14 days,makes the overall result for 1993

2)0.6, since the probability for 14 days in 1993= ,50/100= 0.5 and for 7 days in 1993= 12/100=0.12 sotl total is .5+.12= .62~ 0.6

The combined probability that a tourist chosen at random had stayed either 7 or 14 days on the island was highest :
1.Check the probability for stay at 7th day and 14th day. Since, the question says OR..Add these 2 probabilities.
2. This does not mean to find the average of all probabilities.

They’re mutually exclusive events. A tourist can’t stay both 7 and 14 days, so the total probability is P(7) + P(14).
