when buying a new dress you have a choice of 3 different lengths 5 different colors and 2 different styles. how many choices are there for one dress?

You could draw a tree diagram it has three branches for the different lengths, then from each of those branches it has 5 branches for the different colours, and from each of those branches it has 2 different styles : )

so... 3 x 5 x 2 is the total number of final branches (thus the total number of choices.)

30 is the answer :)

30

I can confirm it is 30, thank you!

How many different ways can the students at the school select the president, vice president and secretary from a group of five people?

The number of ways the students at the school can select the president, vice president, and secretary from a group of five people is given by the formula for permutations:

P(n,r) = n! / (n - r)!

where n is the total number of people to choose from and r is the number of people to select.

For this problem, we have:

n = 5 (since there are five people)
r = 3 (since we need to select three people- president, vice president, and secretary)

Using the formula for permutations, we get:

P(5,3) = 5! / (5 - 3)!
P(5,3) = 5! / 2!
P(5,3) = (5 x 4 x 3 x 2 x 1) / (2 x 1)
P(5,3) = 60 / 2
P(5,3) = 30

Therefore, there are 30 different ways the students at the school can select the president, vice president, and secretary from a group of five people.
