There are 160 pages in a book.15% of the pages having pictures on them. How many
2 answers:
We need to find out how much 15 percent of 160 is. Then, we can subtract that amount by 160. We can use proportions to solve this. We can set up our first fraction with x/160. Our next fraction can be 15/100. We can cross multiply, 160*15. 160*15 is 2,400. 2,400/100 is 24. This means 24 pages have pictures in them. 160-24 is 136. 136 pages do not have pictures on them.

Since A= driver is under 25 years old (1)
B = driver has received a speeding ticket (2)
a.The probability the driver is under 25 years old and has recieved a speeding ticket.

P(AnB)
b. The probability a driver who is under 25 years old has received a speeding ticket.
This is a conditional probability, probability that B will occur given that A as occur.
P(B|A)
c. the probability a driver who has received a speeding ticket is 25 years or older.
