For this question, we're told that martina rolled a number cube 1 ,000 times and got the following results.
00:05
They're summarized there in the table.
00:08
For part a, it says, what's the experimental probability of rolling a 1? what's the experimental probability? so probability of roll 1 is going to be 155 over 1 ,000.
00:24
So out of the 1 ,000 rolls, we got 155 1's, which in percentage form would be 15 .5%.
00:35
And why do i do the percentage? we'll see here in a second.
00:38
So part b says, assuming that the cube is fair, compute the theoretical probability.
00:43
So here's the theoretical probability of roll 1.
00:46
So they're both probability of roll 1, 1's theoretical, 1's experimental.
00:49
That is going to be 1 6, right? there's one side out of 6.
00:53
That's a 1.
00:53
And this is 16 .6 repeating percent...
