A bag contains 2 blue, 5 yellow, and 1 black tile. What is the probability of drawing a blue tile followed by a black tile if the first til drawn is not replaced.
A.1/32
B.1/28
C.1/12
D.1/8

B.1/28

Step-by-step explanation:

The bag contains 2 blue, 5 yellow, and 1 black tile.

The total number of tiles in the bag is

n(S)=2+5+1

n(S)=8

The number of blue tiles in the bag is

n(B)=2

The number of black tile is

n(Bk)=1

The probability of choosing a blue tiles is

The probability of choosing a black tile without replacing the first tile is:

The probability of drawing a blue tile followed by a black tile if the first tile drawn is not replaced

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
