Solution
| C1 Probability |
C2 Written Description |
| (a) 0.95 | (iv) Very likely to happen |
| (b) 0.02 | (v) Very little chance of happening |
| (c) – 0.3 | (i) An incorrect assignment |
| (d) 0.5 | (iii) As much chance of happening as not |
| (e) 0 |
(ii) No chance of happening |
Explanation:
(i) 0.95 = Very likely to happen, so it is close to 1.
(ii) 0.02 = Very little chance of happening as the probability is very low.
(iii) – 0.3 = an incorrect assignment because probability is never negative.
(iv) 0.5 = as much chance of happening as not because sum of chances of happening and not happening is one.
(v) 0 = no chance of happening.
