Answer:

Distance between A ----> B : 2 cm

B ---> C: 3 cm : 600 meters

A----> C: 4 cm

3:600 meters scaled

So its 200 meters per every 1 cm!

From A to B : 400 meters

From B to C : 600 meters

Frok C to A: 800 meters

Therefore we sum 400+600+800= 1800 meters

A person bets 1 dollar to b dollars that he can draw two cards from an ordinary deck of cards without replacement and that they
sertanlavr [38]

Answer:

$3.25

Step-by-step explanation:

In an ordinary deck of cards, we will notice that there are 52 cards.

However, we have 4 suits and 13 cards in each one making a total of 52, right?.

So, the probability that a person draws two cards and they will be of the same   suit is:

P(X) =\dfrac{ \bigg (^4_1 \bigg) \times \bigg ( ^{13}_{2}\bigg) }{ \bigg ( ^{52}_{2} \bigg)}

P(X) =\dfrac{  \dfrac{4!}{1!(4-1)!} \times \dfrac{13!}{2!(13-2)!}  }{ \dfrac{52!}{2!(52-2)!} }

P(X) =\dfrac{4}{17}

Given that; A person bets 1 dollar to b dollars;

To make the bet fair is;

\dfrac{4}{17}b - \dfrac{13}{17}(1) = 0

= \dfrac{4}{17}b = \dfrac{13}{17}

multiply both sides by 17

4b = 13

b = 13/4

b = 3.25

Therefore, to make the fair, the value of b need to be $3.25
