Answer:

171

Step-by-step explanation:

USING GOOGLE, THE POSSIBLE NUMBERS THAT ADD UP TO 343 ARE...

1 + 342 = 343

2 + 341 = 343

3 + 340 = 343

...

169 + 174 = 343

170 + 173 = 343

171 + 172 = 343

THERE ARE MORE NUMBERS BUT THE QUESTION STATES THAT THE TWO PAGES FACE EACH OTHER IN THE BOOK SO, WE ARE LOOKING FOR NUMBERS THAT A NEXT TO EACH OTHER.

USING OF THE NUMBERS LISTED ABOVE, WE ARE ABLE TO DEDUCE THAT 171 AND 172 ARE THE TWO THAT ADD UP 343, SINCE WE ARE LOOKING FOR NUMBERS THAT ARE BESIDE EACH OTHER.

NOW THINKING OF A BOOK, WHEN PAGES ARE NUMBERED THE SMALLER NUMBERED PAGE COME FIRST.

THEREFORE, THE NUMBER OF THE PAGE THAT COMES FIRST IS 171.

PLEASE, THANK, RATE 5 STARS, AND GIVE BRAINLIEST. THANK YOU.

Answer:

171

Step-by-step explanation:

I divided 340 first and got 170 for each page number then I had 3 left over.

I added 1 to 170 and got 171 the I added the left over 2 to the other 170 and got 172.

So the first page number should be 171 :)

I hope this helped you understand :)

Using probability concepts, it is found that P(S and D) = 0.1275.

-----------------------

A probability is the number of desired outcomes divided by the number of desired outcomes.
In a standard deck, there are 52 cards.
Of those, 13 are spades, and 13 are diamond.

The probability of selecting a spade with the first card is 13/52. Then, there is a 13/51 probability of selecting a diamond with the second. The same is valid for diamond then space, which means that the probability is multiplied by 2. Thus, the desired probability is:

$P(S \cap D) = 2 \times \frac{13}{52} \times \frac{13}{51} = \frac{2\times 13 \times 13}{52 \times 51} = 0.1275$
