How to solve simple probability problems in genetics

Probability is the measure of the likelihood that an event will occur. See glossary of probability and statistics. Probability quantifies as a number between 0 and 1, where, loosely speaking, 0 indicates impossibility and 1 indicates certainty.

I just want to make a subtle distinction here that had me really confused. When I first read the question, I thought you were asking "what is the probability that one child out of the five will have albinism", but after watching and re-reading the question, I realized what you are asking (minimum one child could have disease, in any order). Just putting this here in case others were confused. Thanks for the videos.

Oh I see what the question is now. The probability for albinism goes up as they have more children. Really interesting.

I'm not watching this for school but I'm really interested in knowing more about it because I didn't study in school much about this!🤝

[@thabzizi]

You're amazing ❤. It made so much sense and I realized my mistakes

[@abdulwahabaltheeb4861]

why you chose 3/4 not 1/4 can you explain it more to me please?

[@milagrosavalos9675]

cuz is more short to make the multiplication

I think through bionomial formula the calculations is wromg and the probability is 0.39 or 39 percent

[@shrirams7472]

Even i got the same Thought u am the only one😀 But which one is correct can we use binomial in this provlem

Good job. ❤

[@welkingunther4298]

What would the answer or steps be if the question asked for at least 2 children with albinism

[@GeneticsLessons]

I have many more examples including the question you asking - please check "probability and statistics" playlist on my channel.

This was very helpful, thank you.

[@nishunisha4466]

Thank u sir

[@hibakaleem5610]

very clear

[@sowjanyajadi2560]

Sir.. can you give some more detailed at 3rd step..

Having my uni exams tmrw .... 😅😅😅thanks for a brief account

[@GeneticsLessons]

Most welcome 😊

[@GeneticsLessons]

What you got?

[@mentarikasih8677]

how about two child will be albino?

[@shrirams7472]

Why not use binomial equation. The answer I get using binomial is 39%

[@GeneticsLessons]

I recommend you to watch the video to the end, may be you would be able to find your mistake on your own.

[@GeneticsLessons]

Do not forget that probability of the one event is 3/4 and of the second 1/4 - this is where you made a mistake.

[@shrirams7472]

I think the answer we get using binomial equation is , for 1 child with albinism but here it is atleast one so it allows more than one child to have alBinism Hence the probability increases from 39 to 76

[@GeneticsLessons]

Sure "at least 1 means": probability of effected as 1, 2, 3, 4, 5 combined, the only combination which is excluded would be when all 5 children would be healthy.
