For a)
The chances of rolling a 6 are $\displaystyle \frac{1}{6} $ i think.
Rolling a number greater than 4. It should be either 5 or 6 then, but we already have 6 so it will be only 5 that is left $\displaystyle \frac{1}{6} $
Add them together.
$\displaystyle \frac{1}{6} + \frac{1}{6} = \frac{2}{6} = \frac{1}{3} $
For b)
Rolling a number less than 5. It should be 1;2;3 or 4 then, so it will be $\displaystyle \frac{4}{6} $
An odd number. It should be 1;3 or 5 then, but we already have 1 and 3. Only 5 remains, so it will be $\displaystyle \frac{1}{6} $
Add them together.
$\displaystyle \frac{4}{6} + \frac{1}{6} = \frac{5}{6} $
For c)
The chances of rolling a 3 are $\displaystyle \frac{1}{6} $
An even number. It should be 2;4 or 6 then, so it will be $\displaystyle \frac{3}{6} $
Add them together.
$\displaystyle \frac{1}{6} + \frac{3}{6} = \frac{4}{6} = \frac{2}{3} $
That's not me. Probability isnt my strong point. Jhevon helped me, so give him credit... I made mistakes.Originally Posted by mkcar
