Amy has 20 necklaces in a jewelry box. The probability of reaching into the jewelry box and pulling out a silver necklace is 0.85. What is the probability that Amy will reach in the jewelry box and pull out a necklace that is not silver?

0.15

Step-by-step explanation:

Given

Represent the probability of pulling out silver with p; So:

Required

Determine the probability of not pulling silver

This question is to test probability complements

And the complement rule of probability states that:

Where q and p are opposites. In other words:

q = probability of not pulling out silver

Substitute 0.85 for p in

Make q the subject

Hence, the required probability is 0.15

0.15

Step-by-step explanation:

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
