1. how do you find p(a and b) if a and b are dependent events for two or more actions, such as selecting two candies and drawing p(green, and then pink)?

You multiply them.

Step-by-step explanation:

If you have 1/4 chance of getting a blue candy, 1/2 chance of red candy, and 1/4 chance of green candy, and you want to find P ( blue and green ), then you multiply 1/4 * 1/4 = 1/16

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
