Liang Xiao and five other students took part in the 100 meter race. There are 6 runways (1, 2, 3, 4, 5, 6) in the stadium, and the runners decide their races by drawing lots at random.

A.

Test analysis: ∵ There are 1, 2, 3, 4, 5 and 6 runways in the stadium.

∴ Liang Xiao draws lots first, so the probability that Liang Xiao draws 1 runway is:

So choose a.
