3(x + 8)(x – 1)

3(x + 6)(x – 3)

3(x + 5)(x – 3)

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)?
