Check my work....

Here is a problem we had for my stats class and just want to make sure I did it right. This problem seems juvinille compared to what we had been doing so due to it's simplicity I was unsure if I went about it the right way. Anyways...

Problem 1- find the probability of rolling a one given four dice. (This is just (1/6)*4 right?)

Problem 2- find the probability of rolling double one's given 24 trials of rolling two dice. (this is just (1/36)*24 right?) Thanks in advance.

In both cases I assumed that you meant the chance of rolling at least one.
