|
A u B |
That either A or B or both occur |
|
P(B/A) |
Prob that b will occur given that A as already happened |
|
P(AnB)=0 |

Y=a+bx |
|
Why use coding |
To simplify calculations |
|
Interpolation and extrapolation |
Interpolation - when the x value is in range so a reliable estimate Extrapolation- when the x value is out of range so not a reliable estimate |
