1/7 divided by what gives you 14

1 answer:

5 0

(1/7) / x = 14 ....multiply both sides by x, this eliminates the x on the left
1/7 = 14x...divide both sides by 14
(1/7) / 14 = x
1/7 * 1/14 = x
1/98 = x <===

Answer: 1020 ways

Step-by-step explanation:

Let C= comedy

Let M= Mystery

Number of movies(comedy) = 10

Number of movies (mystery) = 10

The total number of movies from which selection is to be made is 10 + 10

= 20

We want to pick 3 movies from 10 comedies and 10 mysteries with at least one mystery.

The selection will be from;

Unconditional selection - (0 mysteries)

=unconditional selection - ( all comedy included)

= 20C3 - 10C3 For combination, [nCr = n! /(n-r) r! ]

= [20!/(20-3)!3!] - [10!/(10-3)!3!

= (6840/6) - (720/6)

= 1140 - 120

= 1020 ways
