Sample NECO SSCE Mathematics 2016 questions

1. A bag contains 5 red balls and 3 blue balls. If one ball is selected at random, what is the probability that it is red?
  1. 3/8
  2. 5/8
  3. 5/3
  4. 1/2

Answer: B. 5/8

There are 5 red balls out of 8 balls in total, so the probability is 5/8.

2. What is the mean of 4, 7, 9 and 10?
  1. 7
  2. 8
  3. 30
  4. 7.5

Answer: D. 7.5

The sum is 30 and 30 divided by 4 is 7.5.

3. The points P and Q have coordinates (2, -1) and (7, 3) respectively; what is the vector PQ?
  1. (5, 4)
  2. (9, 2)
  3. (-5, -4)
  4. (4, 5)

Answer: A. (5, 4)

Subtracting the coordinates of P from those of Q gives (7 - 2, 3 - (-1)) = (5, 4).

4. What is the determinant of the matrix [[3, 2], [5, 4]]?
  1. 14
  2. -2
  3. 2
  4. 22

Answer: C. 2

The determinant is (3 x 4) - (2 x 5) = 2.

5. What is the image of the point (3, -2) under reflection in the y-axis?
  1. (3, 2)
  2. (-3, 2)
  3. (2, -3)
  4. (-3, -2)

Answer: D. (-3, -2)

Reflection in the y-axis changes the sign of the x-coordinate but leaves the y-coordinate unchanged.
