People have the same opportunity to see a solar eclipse as a lunar eclipse.

More people see a lunar eclipse. Since the Sun is so much larger than the Moon, the Moon only blocks out the Sun for about 12 minutes over a relatively small amount of land area on Earth; lunar eclipses can last a couple hours and are seen by a significantly larger area on Earth.

More people see a solar eclipse. Since the moon is between the sun and the Earth more often than the Earth is between the moon and sun, the moon blocks the sun for a solar ecliplse more often.
