Alex makes the 2400 roll. Approximately how many times she should get a four with a normal dice
The propability to get one specifik number with a dice is $${\mathtt{P}} = {\frac{{\mathtt{1}}}{{\mathtt{6}}}}$$ because there is one specifik number out of 6 possible. the propability for even numbers is 3/6 because there is 3 "whished" numbers outof 6 possible.
However, if you roll the dice 2400 we can expect that 1/6 of all rolls would be a four.
So you just multiplie 2400 with 1/6.
I hope you find this helpfull! :)
$$\\\\$Yes HeadingNorth is right$\\\\
\\\frac{1}{6}\;is\;the\;answer\;\mathbf{simplified}\\\\
\\$To be precise, 6\times400=2400 and 1\times400=400$\\
\\$So\; \frac{400}{2400}$$
