From the five-occasion chart, what is the combined percentage for Christmas and Birthday?

0.55

Combining two categories on a chart means adding their percentages to find the total share those categories represent together. For a five-occasion chart, each occasion has a portion of the whole, and the combined percentage for two occasions is simply the sum of their individual percentages.

In this case, the numbers for Christmas and Birthday add up to 0.55, which means 55% of the whole. That’s why 0.55 is the correct total. The other options would reflect different sums that don’t match the chart’s data for those two occasions.

0.65

0.45

0.35
