Since each of the 4 balls are equally likely, their probability is:

From
, we have:


So, the total arrangement of the 8 balls is:




The individual probability of each ball, when put together is




Lastly:




Answer:
v=60
Step-by-step explanation:
10=v/3-10
Subtract 10 from both sides the divide ( however really multiply by the reciprocal.
You can do 2(2*12) or 4(1*6), personally I think the second one is better. Hope this helps!
-8=2-4y
-10=-4y
y=5/2 or 2 1/2 or 2.5
8X5000 is 40000. There's three zeroes in5000 and no zeroes in 8, yet there are 4 zeroes in the answer. This is because you must multiply the non-zeroes, and then add the zeroes from your factors. 8 times 5 is 40, add 3 zeroes to get 40000.
Hope this helps!
