Neco Model Questions Vol1 2020 Geography Question 42
Practice objective / multiple choice question 42 from the 2020 Neco Model Questions Vol1 Geography examination.
A geological survey of a 200 km² region shows that igneous rocks cover 35\% of the area, sedimentary rocks 45\% and metamorphic rocks the remainder. Within the sedimentary rocks, 60\% are clastic and the rest are chemical. Within the metamorphic rocks, 70\% are foliated. Ten percent of the igneous area is covered by vegetation that masks the rock surface, making it unsuitable for mining. If a geologist randomly selects a point that is both exposed rock and lies on foliated metamorphic rock, what is the probability (as a percentage, to one decimal place) that the point meets these conditions?
