A. Since the tosses are independent, we can just calculate the probability of obtaining one head and repeating that 3 times. Obviously, the probability of getting a head for one toss is 1/2, our answer is <em><u> 1/2⋅1/2⋅1/2=1/8</u></em>

B. Suppose you have a fair coin: this means it has a 50% chance of landing heads up and a 50% chance of landing tails up. Suppose you flip it three times and these flips are independent. What is the probability that it lands heads up, then tails up, then heads up? So the answer is <em><u>1/8, or 12.5%.</u></em>

Pam typed 2.5 pages in 15 minutes. At that rate, how many minutes will it take her to type 23 pages?
NeX [460]
In the given question, it is already mentioned that Pam takes 15 minutes to type 2.5 pages. this information should be used as the main information for reaching the desired answer.
Pam typed 2.5 pages in = 15 minutes
Then time taken by Pam to type 23 pages = (15/2.5) * 23
                                                                     = 345/2.5
                                                                     = 3450/25
                                                                    = 138
So Pam will take 138 minutes to type 23 pages
