Answer:

85.71% chance of randomly selecting a student who owns at least one laptop or one desktop

Explanation:

Out of a total of 70 students, only 10 own neither a laptop nor a desktop. This means that the probability of selecting a student with at least one of the two is
(60)/(70) or
(6)/(7).

If we convert this fraction into a percentage and round to the nearest hundredth, it equals:

85.71%
