Abag contains five batteries, all of which are the same size and are equally likely to be selected. each battery is a different brand. if you select three batteries at random, use the counting principle to determine how many points will be in the sample space if the batteries are selected
a) with replacement.
b) without

A. 1/125 or 0.8%

B. 1/60 or 1.7%

Step-by-step explanation:

1. Let's review the information provided to us to answer the questions correctly:

Number of batteries in the sample = 5

2. If you select three batteries at random, use the counting principle to determine how many points will be in the sample space if the batteries are selected

A) with replacement. ?

B) without replacement.?

A . With replacement

First selection = 1/5

Second selection = 1/5

Third selection = 1/5

Probability of selecting three random batteries with replacement = 1/5 * 1/5 * 1/5 = 1/125 or 0.8%

B. Without replacement

First selection = 1/5

Second selection = 1/4

Third selection = 1/3

Probability of selecting three random batteries without replacement = 1/5 * 1/4 * 1/3 = 1/60 or 1.7% (Rounding to the next tenth)

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
