Probability with and without replacement:

an activity book has 21 pages of crossword puzzles, 18 pages of cryptograms, and 12 pages of mazes. bianca randomly selects a page, completes the activity, and then randomly selects another page to complete.

what is the probability that bianca first completes a maze and then completes a crossword puzzle.

ans:

42/425

28/289

21/88

33/51

28/289

Step-by-step explanation:

First we need to find the total number of pages.

21 = crosswords puzzles

18 = cryptograms

12 = mazes

So there are:

21 + 18 + 12 = 51 pages total

The probability that Bianca will complete a maze first is 12/51.

The probability that her next choice will be a crossword puzzle is 21/51

Now to find the probability that Bianca will do a maze followed by a crossword puzzle is:

12/51 x 21/51

We can simplify the values by dividing everything by 3

Maze then crossword puzzle = 4/17 x 7/17

Maze then crossword puzzle = 28/289

step-by-step explanation:

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
