The J. O. Supplies Company buys calculators from a Korean supplier. The probability of a defective calculator is 10%.If 10 calculators are selected at random, what is the probability that 3 or more of the calculators will be defective?
A. 0.0702
B. 0 .2639
C. 0.0016
D. 0

A. 0.0702

Step-by-step explanation:

The probability that 3 or more of the calculators will be defective is 1 minus the probability that exactly zero, one or two calculator are defective:

For X= 0:

For X= 1:

For X=2

Therefore:

The probability that 3 or more of the calculators will be defective is 0.0702.

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

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
