ax) = x - 5x2 - 16x+ 20
f(x) = x2 - 5x2 + 16x - 80
ax) = x2 - 5x + 11x – 80
f(x)= x + 5x2 - 16x - 80

How do you find p(a and b) if a and b are independent events for two or more actions, such as tossing a coin twice and finding p(heads and heads)? 2. how do you find p(a or b) if a and b are independent events for one action, such as spinning a four-color spinner once and finding p(red or blue)?
