Question

The probability of drawing a pearl bead out of a bag of mixed beads is 2/3. What is the probability of drawing a bead which is not a pearl?

Answer 1

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
