Joe is shown 3 cards marked 2 ,5, and 9, he selects these in random order, to give a three digit score. What is the sum of all possible scores

3,552

Step-by-step explanation:

The possible scores are

259, 295,529, 592, 952, 925

These are all the possibilities from his selection. Hence the sum of all possible scores may be computed as

= 259 +295 + 529 + 592 + 952 + 925

= 3,552

the sum of all possible scores is 3,552

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
