Answer:
26/51
Step-by-step explanation:
Probability Formula = No of possible events ÷ Number of events
We are given a standard deck of 52 cards. Hence,
The number of events = 52
It is important to note that in a standard deck of 52 playing cards,
26 are red
26 are black
WITHOUT REPLACEMENT
Probably of drawing
a red card = 26/52 = 1/2
We are asked to find the probability of drawing a second card that is black
Probability of drawing a black card = No of possible outcomes / Number of events
Number of possible outcomes = 26 Due to the fact that the red card after been drawn was not replaced,
Number of events = 51
Hence , Probability of drawing a black card = 26/51
Therefore, the Probability of drawing a black card =
P (black ) = 26 /51
Answer:
B
Step-by-step explanation:
If you take 647.50 and subtract it by 671.92 which gives you -24.42 but just take away the negative sign
C! 80 + 10 is 90, 90+90 is 180. There are 180 degrees in one triangle
Answer:
Step-by-step explanation:
To find the inverse function switch variables out and solve for y
If
y=(x+3)/x swap variables to get
(y+3)/y=x then solve for y
y+3=yx
y-yx+3=0
y-yx=-3
y(1-x)=-3
y=-3/(1-x)
y=3/(x-1)
