A tyre company records distances before replacement in 1000 cases. Find the probability that a randomly chosen tyre lasts:
(i)
Less than 4000 km.
Answer
0.02
(ii)
Between 4000 and 14000 km.
Answer
0.535
(iii)
More than 14000 km.
Answer
0.445
Explanation
The problem requires calculating the experimental probability for different distance ranges using the formula P = (Number of favourable outcomes) / (Number of possible outcomes). The total number of possible outcomes is the total number of cases recorded, which is 1000. For each sub-part, we identify the number of favourable outcomes from the given table and divide it by 1000 to find the probability.
