Probability. We are randomly lining up 4 ranchers and 3 shepards, for a total of seven people.

What is the probability that the line will alternate between ranchers and shepards?

Step-by-step explanation:

Given: We need to line up 4 ranchers and 3 shepherds, for a total of seven people.

i.e. we are placing all of them , so we have 4 places for ranchers and 3 places for shepherds between them.

Number of ways to line up alternate between ranchers and shepherds = 4! x 3!

= 24 x 6

= 144

Total number of ways to line up 7 persons = 7! = 5040

Required probability =

Hence, the probability that the line will alternate between ranchers and shepherds =  

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
