Hello students, we'll start our video.

The solution to this question is, if a couple have five children, what will be the probability of all the children are colorblind or that none of the children are colorblind? when finding probabilities within or statement, you must add the probabilities of each.
00:27
The question asks for probability of getting a colorblind child.
00:32
Child, that is to say the children who actually get colorblind and are not just the carriers of the disease.
00:41
If you cross a colorblind male with a carrier female, you will get x, c, y with x, c, x, x, so we get 1 4th r x c, x, c, that is colorblind, 1 4th r x c, x, that is not colorblind, 1 4th r, x, x, that is not colorblind, 1 4th r, r, x, that is not colorblind, 1 4th r, x, c, y, which are colorblind and one fourth are x, y which are not colorblind.
01:21
Here one fourth that is x, c, x, this is the carrier.
01:31
Here total of 2 by 4 offspring were color blind and 2 by 4 are not color blind...
