Answer:

0.15

Step-by-step explanation:

<u>Independent Probabilities Formula</u>

P(A | B) = P(A) = P(A ∩ B) ÷ P(B)

P(A | B) = 0.25

P(A) = 0.25

P(B) = 0.6

If P(A) = P(A ∩ B) ÷ P(B)

P(A ∩ B) = P(A) × P(B)

P(A ∩ B) = 0.25 × 0.6

P(A ∩ B) = 0.15

Licemer1 [7]

Answer:

17/49 or about 34.7%

Step-by-step explanation:

George has 85 cards out of 245 cards that are pitchers. Whever you hear "out of", it means to divide.

85/245 are pitchers.

you can simplify since 5 fits in both of those numbers

5*17=85

5*49=245

So, 17/49 or about 34.7%

Answer:

yes

Step-by-step explanation:

youre trying to find when -1/4x + 3/2 = -x+ 3

so if you set it up like that and then solve for x you get 2

then, you know that 2 is your x value so just plug in x into one of the equations to get the y value

(i used -x+3 bc its easier)

-2+3=y

y= 1

so your solution is (2,1)
