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.
