Question 22

Probability

The table shows the distribution of the distance (in km) covered by 40 hunters while hunting.
Distance (km): 3, 4, 5, 6, 7, 8
Frequency: 5, 4, x, 9, 2x, 1
If a hunter is selected at random, find the probability that the hunter covered at least 6 km.

  1. A.3/5
  2. B.2/5
  3. C.3/8
  4. D.9/40
Show the answer and explanation

Answer: A (3/5)

Explanation

19 + 3x = 40 gives x = 7. Hunters covering 6 km or more: 9 + 14 + 1 = 24. P = 24/40 = 3/5.
