Sample NECO SSCE Mathematics 2026 questions

1. Two fair six-sided dice are thrown together; what is the probability that their scores sum to 8?
  1. 1/6
  2. 5/36
  3. 1/9
  4. 1/12

Answer: B. 5/36

The five ordered outcomes summing to 8 out of 36 equally likely outcomes give a probability of 5/36.

2. Find the mean of 6, 9, 11 and 14.
  1. 10
  2. 9
  3. 11
  4. 12

Answer: A. 10

The sum is 40 and dividing by the four observations gives a mean of 10.

3. What is the median of the ordered data 2, 4, 5, 8, 10, 13?
  1. 5
  2. 7
  3. 8
  4. 6.5

Answer: D. 6.5

For six observations the median is the mean of the third and fourth values, (5 + 8)/2 = 6.5.

4. Find the range of the data set 19, 8, 12, 15, 11.
  1. 8
  2. 10
  3. 11
  4. 12

Answer: C. 11

The range is the maximum minus the minimum, so 19 - 8 = 11.

5. If sin θ = 3/5 and θ is acute, what is cos θ?
  1. 3/4
  2. 4/5
  3. 5/4
  4. 2/5

Answer: B. 4/5

The 3-4-5 right triangle gives the adjacent-to-hypotenuse ratio cos θ = 4/5.
