pav-90 [236]

Answer:

$\frac{2}{11}$

Step-by-step explanation:

First, find the probability of him pulling out a book.

There are 11 objects in total, and there are 4 books.

So, the probability of pulling out a book is $\frac{4}{11}$

Next, find the probability of him pulling out a DVD after.

Since a book was taken out, there are only 10 objects left. There are 5 DVDs.

So, the probability of pulling out a DVD is $\frac{5}{10}$ , or simplified to $\frac{1}{2}$

To find the probability that this happens in order, multiply the probabilities:

$\frac{4}{11}$ x $\frac{1}{2}$

= $\frac{2}{11}$

So, the probability is $\frac{2}{11}$

Question 2<br> Answer<br><br> Solve

Lelu [443]

<u>Answer:</u>

Option B is correct.

<u>Step-by-step explanation:</u>

<u>To subtract fractions, we must check if the denominators of both fractions are the same.</u>

2/5 - 1/7
=> 2 x 7/5 x 7 - 1 x 5/7 x 5
=> 14/35 - 5/35

<u>Now, let's subtract for the result.</u>

=> 9/35

Hence, <u>Option B is correct.</u>

Hoped this helped.

You purchase a $220 Arline ticket. You have a discount code to receive 10% off. There is a 10.5% service charge added to the tot

antoniya [11.8K]

When you see % next to a number, you multiply it by .01.
10 becomes .1
10.5 becomes .105

220*.1=22, so this is the 10% off
220*.105=23.1, so this is the 10.5% service charge.

220-22+23.1=$221.10 for the ticket.
