A box contains 22 widgets 4 of which are defective. If 4 are sold at random find the probability that a all are defective b none are defective

Probability that all 4 are defective is

0.181818181 and the probability that none of them us defective is 0.818181818

Step-by-step explanation:

The question Here says that A box contains 22 widgets 4 of which are defective. If 4 are sold at random find the probability that a all are defective b none are defective

The probability of all 4 widgets sold being defective is 4/22 = 0.181818181

And the probability of all 4 being effective will be

1 - (4/22)

= 9/11 or 0.818181818

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
