Answer:

\frac{1}{3} probability of drawing a bead which is not a pearl

Step-by-step explanation:

For each bead that you draw, there are only two possible outcomes. Either it is a pearl bead, or it is not. The sum of these probabilities = 100% = 1.

So

2/3 probability of drawing a pearl bead.

p probability of drawing a non pearl bead.

What is the probability of drawing a bead which is not a pearl?

p + \frac{2}{3} = 1

p = 1 - \frac{2}{3}

p = \frac{3*1 - 2}{3}

p = \frac{1}{3}

\frac{1}{3} probability of drawing a bead which is not a pearl

What is the amplitude of this graph?
Alexxandr [17]
<h3>Answer:  2</h3>

The lowest point has a y coordinate of 2. The highest point has a y coordinate of 6. The difference is 6-2 = 4. Cut this in half to get 4/2 = 2 which is the amplitude. This is the vertical distance from the midline (y = 4) to either the peak point or the valley point.
