Question 3 is [tex] \frac{1}{3} [/tex]. There are two numbers greater than 4 (5 and 6), so the probability would be [tex] \frac{2}{6} [/tex]. Dividing the numerator and denominator by 2 will simplify it to [tex] \frac{1}{3} [/tex].
Question 4 is [tex] \frac{1}{6} [/tex]. There is only one number greater than 5, which is 6. This is already in simplest form.
Question 5 is [tex] \frac{2}{3} [/tex]. There are four numbers greater than 2, which are 3, 4, 5, and 6. This makes the probability [tex] \frac{4}{6} [/tex], which simplifies to [tex] \frac{2}{3} [/tex] when the denominator and numerator are divided by 2.
