A die with faces numbered 1 to 6 is rolled once. What is the probability of obtaining 4?
\(\frac{1}{36}\)
\(\frac{1}{6}\)
\(\frac{1}{3}\)
\(\frac{1}{2}\)
\(\frac{2}{3}\)
Correct answer is B
When the die is rolled, occasion of getting 4
P(obtaining a 4) = \(\frac{1}{6}\)
= \(\frac{1}{6}\)

Express as a single fraction: \(\frac{x}{x-2}-\frac{x+2}{x+3}\)
\(\frac{2x^2 - 3x - 4}{(x-2)(x+3)}\)
\(\frac{2x^2 + 3x - 4}{(x-2)(x+3)}\)
\(\frac{2}{(x-2)(x+3)}\)
\(\frac{ 3x + 4}{(x-2)(x+3)}\)
\(\frac{3x - 4}{(x-2)(x+3)}\)
Correct answer is D
\(\frac{x}{x-2}-\frac{x+2}{x+3}\)
\(\frac{[x][x+3] - [x+2][x-2]}{[x-2][x+3]}\)
= \(\frac{x^2 + 3x - x^2 - 4}{[x-2][x+3]}\)
= \(\frac{3x - 4}{[x-2][x+3]}\)
