HELP ASAP 100 POINTS AND MARKED BRAINLIEST Gary Foshee created a popular probability puzzle that goes like this: “I have two children. One is a boy born on a Tuesday. What is the probability I have two boys?”

In this puzzle, knowing that one of Gary’s children was born on a Tuesday is as important as knowing that he has one boy. Assuming that having boys and girls are equally likely and that births are equally likely on every day of the week, what is the probability that Gary has two boys, given the available information? (Hint: When Gary said that one is a boy born on a Tuesday, he meant at least one child is a boy born on a Tuesday.)

1/2

Step-by-step explanation:

might be wrong with this thinking, but since he already told you he has one boy you just need to look at the probablity that the other is a boy. each kid had a 50% chance. so the remaining kid of unknown gender has a 50% chance of being a boy.

if he did not say one was a boy, it would be 1/2 * 1/2 = 1/4 or 25% that he had two boys

1/2

Step-by-step explanation:

We want to find

P( two boys| one is already a boy)

This is really

P( boy)

We know that you can either have a boy or a girl

P( boy ) = possibility of having a boy/ total options

              = 1/2

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
