Dennis_Churaev [7]

Answer:

"p," the probability of success, is the chance of winning a prize.  This is equal to 50% (1/2).

1 - p, the probability of failure, is the chance of not winning or losing a prize.  This is equal to 50$ (1 - 0.5).

Step-by-step explanation:

When an outcome is obtained from two events, the probability of the outcome happening is 50% (1/2).

On the other hand, the probability of the intended outcome not happening is the difference between 1 and the probability of obtaining the outcome from the two events.  This is statistically expressed as 1 - p.

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
