Imagine I have a well shuffled deck of 52 cards. - If Student A picks a card, the odds that the card is one of the 4 Aces in the deck is 4 in 52, or 1 in 13.
- If the card is placed back in the deck and the deck is reshuffled, the odds that student B picks an Ace is also 1 in 13 - the events are
independent. The first has no effect on the second. That seems fairly obvious hopefully.
- If Student A KEEPS their card and shows everyone that it is a 2 (or anything other than an Ace), then the odds that student B picks the
Ace of Spades CHANGES to 4 in 51 - the events are dependent. The outcome of the first event changes the odds of the second event.
-- Likewise, if student A KEEPS their card and it is an Ace, the odds for Student B change to 3 in 51 or 1 in 17.
But what happens if Student A keeps their card WITHOUT revealing what it is? In the comments section, answer these focus
questions:
What are the odds that student B draws an Ace in this scenario drawing second, but having no knowledge of Student A's draw?
Are these 2 events (Student A draws an ace and Student B draws an Ace) independent or dependent? Justify your answer.

saving = more money

step-by-step explanation:

if you have 100 bucks, and you want to buy a candy bar, even if you have one at home, if you choose not to buy it, you save.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

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.  

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
