Only the one about Emily as the outcomes are equally likely. Two outcomes so probability of one is 1/2.

All the others cannot be calculated.

OP said b, d mentioned on answer sheet - can't see how someone's ranking in a swimming race can be calculated with any certainty unless one knows that there are only three in the race and this girl has never come within a minute of the other two over the distance :?

- actually, scrap that, D is the coin-tossing, I think, because the OP lists A/B/C/C/D so the second C is D.

B is someone passing driving test, though...

Yes, it is not clear what the answer said. The coin tossing is the correct answer as per g55 but it is not clear why two answers were mentioned in that strange way by the o p ?

GL assessment answer sheet is not good. They miss the correct number and put the next answer to the previous one. Really confusing.
