Answer:
P ( blue ) = 1/4
P ( white ) = 5/12
P ( red ) = 1/3
P ( not red ) = 2/3
Step-by-step explanation:
To find the probability of a marble being chosen, it is the number of that color over the total
We need to find the total number of marbles
4 red+ 5 white+3 blue = 12 marbles
P ( blue ) = 3 blue / 12 total = 3/12 = 1/4
P ( white ) = 5 white / 12 total = 5/12
P ( red ) = 4 red/ 12 total = 4/12 = 1/3
How man marbles are not red
total marbles - red marbles = 12-4 = 8
8 marbles are not red
P ( not red ) = 8 not red / 12 total = 8/12 = 2/3
40÷30s? I think that is the answer, but I'm not completely sure...
For 5x-2y=-6 it is 2.5x+3 and for 15x-6y=-6 is 2.5x-1
Answer: 20, I believe
Step-by-step explanation: You already have 500 which is half of 1000. 500 divided by 25 equals 20.
