Answer:

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 
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
, or simplified to 
To find the probability that this happens in order, multiply the probabilities:
x 
= 
So, the probability is 
0.376*800
=(0.376*8)*100
=3.008*100
=300.8
There would be a 10% chance that they would have the same birthday
Answer:
x = 4
Step-by-step explanation: because 13 - 13 u cross them out and u get 17 subtract 13 and ounce u do them u get 4 so then now your left with x so u bring that down and then u get x = 4 hopefully i answered your question or answer have a nice day as well
