Correct Answer: B. A∩B = Ø
Quick factMutually exclusive events cannot happen together, so their intersection is empty.
Explanation
Mutually exclusive events cannot occur together, so they share no outcomes, making their intersection empty (A∩B = Ø). Thus, the probability of both occurring is zero.

10!/7! = ?:
Correct Answer: D. 720
Quick factTen factorial divided by seven factorial equals 720.
Explanation
10!/7! simplifies to 10 × 9 × 8, which equals 720. Factorials cancel the common 7! in numerator and denominator.

45% = 135 → total students:
Correct Answer: A. 300
Quick factIf 45 percent of the students is 135, the whole class numbers 300.
Explanation
Since 45% of the total is 135, divide 135 by 0.45 to get 300. Thus 45% of 300 equals 135.

What is the median of these 7 call durations: 11, 15, 13, 14, 16, 12, 17?
Correct Answer: D. 14
Quick factSorted in order, the middle of those seven call times is 14, the median.
Explanation
After sorting the durations as 11, 12, 13, 14, 15, 16, 17, the middle (4th) value is 14. The median is the central number in an odd-sized ordered dataset.

Solve: 3(x−1)=−6:
Correct Answer: B. -1
Quick factSolving 3(x − 1) = −6 gives x equal to −1.
Explanation
Divide both sides by 3 to get x − 1 = −2, then add 1, yielding x = −1. Checking: 3(−1 − 1) = 3(−2) = −6.

Increase 72→90 percentage:
Correct Answer: D. 25%
Quick factRising from 72 to 90 is an increase of 18, which is 25 percent.
Explanation
Increase is 18, and 18 divided by original 72 equals 0.25, so the percentage increase is 25%. Percentage change uses the formula: change divided by original value times 100.

Painted cube surface area:
Correct Answer: B. 96 cm²
Quick factA cube of side 4 centimetres has a surface area of 96 square centimetres.
Explanation
For a cube with side length 4 cm, total surface area equals 6 × 4² = 96 cm². A cube always has six equal square faces.

If √t = 1/2, evaluate expression:
Correct Answer: D. √(log2/t²)
Quick factIf the square root of t is one half, the expression equals √(log 2 / t²).
Explanation
Since √t = 1/2, t = 1/4 and t² = 1/16. The expression must place the whole quotient under the radical, giving √(log2/(1/16)) = √(16 log2), which matches option D.

Simplify (5p−6q)²+(5p+6q)²:
Correct Answer: A. 50p²+72q²
Quick factExpanding both squares, (5p − 6q) squared plus (5p + 6q) squared equals 50p squared plus 72q squared.
Explanation
Expanding gives 25p²−60pq+36q² plus 25p²+60pq+36q², so the middle terms cancel, leaving 50p²+72q². This uses the identity (a−b)²+(a+b)²=2a²+2b².
