Acompany has determined that 1% of its widgets are defective. if a customer received 2 widgets, what is the probability that they are both defective? a.)1/1,000 b.)1/10,000 c.)1/100 d.)1/10

 The correct option is (B)

Step-by-step explanation:  Given that a company has determined that 1% of its widgets are defective.

We are to find the probability that both widgets are defective, if a customer received 2 widgets.

Let, A and B denote the events that the first widget is defective and the second widget is defective respectively.

Then, we have

The probability that both the widgets received by the customer are defective is given by

Since both A and B are independent events, so we must have

Thus, the required probability is

Option (B) is CORRECT.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
