Hi, i'm david and i'm here to have you answer your question.
00:03
Now let me bring up your question here.
00:07
In the question here, we are going to discuss about the binomial distribution.
00:11
Here, we are given the 60 % of american adults prefer seven hours spending.
00:17
So we will have the b stand for the proportion and equal to the 60 % which is 0 .6.
00:24
We have the symbol size n equal to the 50 and we define the x.
00:31
It will be equal to the number of american adults out of the random sample of 50 who prefer saving the spending so x equal to the number of american adult in the sample of 50 preferring spending and this will be the answer for the part a and then the part p, we want to see x will take the values of.
01:25
It can be 0, 1, 2, 3 until the n will be the 50 of them.
01:33
Now for the question c, we want to find the probability distribution of the x.
01:37
So because x here will follow by the binomial when the n equal to the 50 and the 016.
01:47
And then we will have the probability in the x.
01:51
Equal to the n choose x and then we will have the 0 .6 power x 1 minus 0 .6 power on the n minus x and that's going to be the answer for the c...
