2 ft 7 in
3 ft 11 in
6 ft 9 in
-----------------add
11 ft 27 in........and since 1 ft = 12 inches, then 27 inches = 2 ft 3 inches

so it would become : 13 ft 3 inches <==

In regional spelling bee, the 8 finalists consist of 3 boys and 5 girls. Find the number of sample point the sample space S for

Minchanka [31]

Answer:

i) There are 40320 possible orders

ii) There are 336 possible orders for the first 3 positions.

Step-by-step explanation:

Given: The number of finalists = 8

The number of boys = 3

The number of girls = 5

To find the number of sample point the sample space S for the number of possible orders, we need to find factorial of 8!

The number of possible orders = 8!

= 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8

= 40320

ii) From all 8 finalist, we need to choose first 3 position. Here the order is important. So we use permutation.

nPr = $\frac{n!}{(n - r)!}$

Here n = 8 and r = 3

Plug in n =8 and r = 3 in the above formula, we get

8P3 = $\frac{8!}{(8 - 3)!}$

= $\frac{8!}{5!} \\= \frac{1.2.3.4.5.6.7.8}{1.2.3.4.5}$

= 6.7.8

= 336

So there are 336 possible orders for the first 3 positions.
