Question 1098423
the southern hemisphere is 50% of the surface of the earth, therefore the probability it would hit the southern hemisphere is .5.


20% of the southern hemisphere is land, so the probability that it would hit land in the southern hemisphere is .5 * .2 = .1.


80% of the southern hemisphere is sea, so the probability that it would hit sea in the southern hemisphere is .5 * .8 = .4


south africa takes up 5% of the land in the southern hemisphere, so the probability that it would hit south africa is .5 * .2 * .05 = .005.
