Answer:
3/4 or 75%
Step-by-step explanation:
This is Probability.
The favourable outcome you want is EITHER black OR white
Probability of BLACK + Probability of WHITE = 7/12 + 1/12 = 8/12
Then simplify into 3/4
64
80 80
thats how you havw to put it
A=(3.14d^2)/4
A=0.785d^2
A=0.785(10^2)
A=78.5 yd^2
You can't get a square root of any number that has a negative sign on the inside of the radical
3950÷5=790 (790×5=3950)
1914÷6=319 (319×6=1914)
