Answer:
1/16
Step-by-step explanation:
multiply the separate probabilities. On the number, it's 1/8 chance you'll get 1. On the letter, it's a 3/6 or 1/2 chance you'll get an A.

Answer:
a = d/2b - 2/b
Step-by-step explanation:
2ab+4=d
2ab=d-4
a= d/2b - 4/2b
<h2>a = d/2b - 2/b</h2>
Step-by-step explanation:
Question 3) there's 60 minutes in a hour
3 times 60 = 180 books in 1 hour
3 times 180 = 540 books in 3 hours
540 + 180 + 180 = 900 books in 5 hours
The difference between those numbers : 900-540= 360 and 540-180= 360 so every 2 hours 360 books is done each time so just add 360 books each time for every 2 hours added
