Math Problem!

You have duplicate sets in there. There's only four possible combinations.

ETA: I see you corrected, reading comprehension, Duh! I'll go sit in the corner now!

The only thing I corrected was adding the word "possible" between eight and scenarios right after I first posted lol unless you're referring to something else.

reduces to 3 to 4

I missed that part first time I read it. I was honed on on your combinations, I guess and glossed right over it.

So let's look at the odds of 3 plants all being male (or female).

Let's assume this species is 1/2 male and 1/2 female. So that's 50% odds of a single plant being male (or female). This would then be true for each plant you add to the mix. To figure the chance of them all being male (or female) you multiply the percent chance. So 50%x50%x50% = 12.5%.

So with 3 plants you have a 12.5% of them all being the same sex. Or for what you are asking, an 87.5% chance that they will reproduce.

I understand your rationale, but did you account for the possibility of all males and all females in your calculations? It seems your number of 12.5% only accounts for one of those two possibilities?

By my rational 12.5% is the chance of being all male or all female.

Edit: on further review I see what you mean. There would be a 12.5% chance of being all male AND a 12.5% chance of being all female. Therefore there is a 75% chance of having a mix.

I hate math.....

I gotcha. After you first posted I read back over my post about 100x trying to figure out where I messed up lol

I'm thinking about 75 percent. I can't show my work. My brain has It's own weird way of doing maths.

 

[Okie4570]

That's correct. 50/50 chance of pulling a male or female each time for three pulls.....

All three the same
12.5%
At least one the same
87.5%
Just one the same
37.5%
At least two the same
50%
Exactly two the same
37.5%
None of them the same
12.5%

Yes. I'm STILL YELLING!!!
