maria [59]

Answer: The required probability is 22.5%.

Step-by-step explanation:

Since we have given that

Probability of radio listeners live in Waterville = 0.75

Probability of radio listeners live in Newport = 0.25

Probability of radio station KTBC in Waterville = 0.20

Probability of radio station KTBC in Newport = 0.30

So, using "Multiplication rule of Probability":

Probability that the listener will be tuned in to station KTBC is given by

0.75\times 0.20+0.25\times 0.30\\\\=0.15+0.075\\\\=0.225\\\\=22.5\%

Hence, the required probability is 22.5%.

How many ways can you arrange your 3 statistics books, 2 math books, and 1 computer science book on your bookshelf if (a) the bo
katrin [286]

Answer:

720 different ways.

Step-by-step explanation:

Permutation has to do with arrangement. For example, in order to arrange 'n' objects in any order, this can only be done in n! ways since there is no condition or restriction on how to arrange the objects.

n! = n(n-1)(n-2)... (n-r)!

If there are 3 statistics books, 2 math books, and 1 computer science book on your bookshelf, the total number of books altogether is 3 + 2 + 1 = 6 books.

The number of ways that 6 books can be arranged in any order is 6!.

6! = 6(6-1)(6-2)(6-3)(6-4)(6-5)

6! = 6*5*4*3*2*1

6! = 120*6

6!= 720 different ways.

<em>Hence, the books on your shelf can be arranged in 720 different ways</em>.

or, 15x=165

or, x=11

so, <T = 9×11+21 = 120
