---Question: A museum curator is organizing a digital exhibit featuring 8 historical telescopes and 5 early microscopes. If the exhibit layout requires selecting 3 telescopes and 2 microscopes to display in a row, how many distinct arrangements are possible?
["Title: How Many Distinct Arrangements Are Possible for a Digital Exhibit Featuring Telescopes and Microscopes?", "When curating a dynamic digital museum exhibit, selecting and arranging historical scientific instruments is both an artistic and mathematical challenge. In this case, a museum curator is organizing a special exhibit featuring 8 historical telescopes and 5 early microscopes. To create an engaging display, exactly 3 telescopes and 2 microscopes will be selected and arranged in a row.
