The probability of two events that are not mutually exclusive may be calculated using the formula p(aub) = p(4) + p(b) - p(a b). in other words, the probability of a or b occurring is the sum of the probabilities, minus the probability that a and b occurred.

using this formula, calculate the probability of drawing a black card or any 2, 3, 4, or 5 on a single random draw from a standard
52-card deck

a. 1/2
b. 17/26
c. 19/26
d. 21/26

inch

step-by-step explanation:

yard and mile are too big.

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
