Permutations vs combinations(one step):

Bogdan [553]

Answer:

the expression is: $^{15}P_3=\frac{15!}{(15-3)!}$

and 2730 different ways are possible.

Step-by-step explanation:

In the given question we have to choose a president, vice

president, and secretary.

Permutations are used when order is important so, as in the given question order is required. We would use permutations

The formula used is: $^nP_r=\frac{n!}{(n-r)!}$ where:

n=total number of objects

r=number of objects selected

In our case: n=15, r=3

Putting values and finding the answer:

$^nP_r\\^{15}P_3=\frac{15!}{(15-3)!} =2730 \ ways$

So, the expression is: $^{15}P_3=\frac{15!}{(15-3)!}$

and 2730 different ways are possible.

Lucy watched TV for 25 of an hour on Monday. She watched 79 of an hour on Tuesday. What day did she spend more time watching TV?

notka56 [123]

Hello there,

Lucy watched more TV on Tuesday.

This is because 1 hour = 60 minutes.

so, 25% of 60 min = 15 min on Monday

and, 79% of 60 min = 47.7 min rounded gives 48 minutes on Tuesday...

Hope this answer helps. Good luck.
