In its question, we're given a roulette wheel.
00:04
It spans seven times where we keep track of the winning numbers.
00:09
So does the above result in a binomial distribution? now, i'm going to let x be the winning number for each round.
00:16
So let's take a look at what are the binomial distribution criteria.
00:21
There are four of them.
00:23
The first criteria, the number of trials and is fixed are identical.
00:26
That means every trial is the same.
00:29
Second criteria is trial is independent.
00:31
Third criteria each trial results in one or two outcomes, success and failure.
00:37
So there's only two outcomes in each trial.
00:41
And the last criteria, probability of success in a single trial, remains the same from trial to trial.
00:48
So let's take a look.
00:51
The roulette will expand seven times, so the number of trials will be seven.
00:57
And let's take a look in each trial.
00:59
What's going to be the value of x? now, x can be any value for the number.
01:06
Each trial, each round, as long as it's within the roulette numbers of 0 -0.
01:13
So it could be either 0 or 0 or 1, 2, 3 all the way to 18...
