In how many ways can a photographer at a wedding arrange six people in a row, including the bride and groom, if a) the bride mus

ELEN [110]

Answer: a) 240, b) 480, c) 360

Step-by-step explanation:

Since we have given that

Number of people = 6

Number of bride and groom = 2

So, remaining people = 6-2 = 4

So, using the fundamental theorem of counting

remaining people can be arranged in

$4!=4\times 3\times 2\times 1=24$

Since bride has 5 positions to stand and grooms too has 5 positions to stand.

so, Number of positions for both bride and groom = 5+5=10

So, a) the bride must be next to the groom?

Number of ways = $24\times 10=240$

b) the bride is not next to the groom?

Total number of ways would be

$6!=6\times 5\times 4\times 3\times 2=720$

So, Number of ways that the bride is not next to the groom is

$720-240=480$

c) the bride is positioned somewhere to the left of the groom?

If Groom is in second position, bride has 1 ways to stand

If Groom is in third position , bride has 2 ways to stand

If Groom is in fourth position, bride has 3 ways to stand

If Groom is in fifth position, bride has 4 ways to stand

If Groom is in sixth position, bride has 5 ways to stand.

So, Number of ways to stand = 1+2+3+4+5=15

So, the total number of ways bride is positioned somewhere to the left of the groom is given by

$24\times 15=360$

Hence, a) 240, b) 480, c) 360

Select the true statement about the series, ¾ + 7/8 + 11/12 + 15/16…

Luden [163]

$\dfrac34+\dfrac78+\dfrac{11}{12}+\dfrac{15}{16}+\cdots=\displaystyle\sum_{n=1}^\infty\frac{4n-1}}{4n}$

The $n$ th term in the series is

$\dfrac{4n-1}{4n}=1-\dfrac1{4n}$

which means for large $n$ , the series behaves asymptotically similar to the series

$\displaystyle\sum_{n=1}^\infty1$

which diverges, so the answer is (B).
