If a dice is rolled four times what is the probability that the same number is rolled at least twice? round your answer to four decimal places and show your work.

Step-by-step explanation:

Let’s try to go this way.

For example the number is k. It can be of course any number. So k is between 1 to 6.

The chance of rolling exactly zero ks is: =625/1296;

The chance of rolling exactly one k is:   * = 500/1296;

So, the chance of rolling less than two ks is: 1125 / 1296;

So, the chance of rolling at least two ks is: 171 / 1296

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.  

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y
