Hi, i'm david and i'm here to help you answer your question.
00:04
Now let me bring up your question here.
00:07
In this question here, when you discuss about the binomial distribution, let me remind you that you will have the x that followed by the binomial with the n and the b.
00:17
And then the probability the x equal to k equal to n choose k b power k times 1 minus b n minus k now in this question here we're given that there five colors in the skittal candies and it will be equally distributed and it means that the probability of its color will be 20 % or it will equal to the z -pon -2 here we're interested in the green color so means that the probability in the green one also equal to the z -pon -2 now we're given the end the number of the candies in the back, it will equal to the 40.
01:03
Now if we call x equal to the number of the green in the back, and then we will see that x will follow by the binomial.
01:21
With the n, it will equal to the 40 and the p equal to the zupon 2.
01:26
The question asks, let you find the probability that we will find that 10 more green in the back.
01:33
So x will be greater equal to the 10.
01:36
To find this probability, we can turn it into the summation.
01:41
So k can go from 10 up to the maximum with the 40 green one.
01:47
And it will apply the formula for the binomial.
01:49
We will have the 40 which is k...
