Hi, i'm david and i'm here to help you and send your question.
00:03
Now let me pick up your question here.
00:05
In the question here, we are going to discuss about the number of arrangements on the six letters can be formed if the first letter must be w or k.
00:14
So let's try to draw the six letters here.
00:17
One, two, three, four, five and six.
00:21
Now for the first letter, it will be either the double yield or the two, 4, 5 and 6.
00:26
Now for the first letter, it will be either the double yield or the k.
00:33
So therefore, for the first one, we have only two choices.
00:37
And then for the second one, we will have totally 26 letters...
