3,4,5

This is a Pythagorean triple. It forms a right triangle

3^2 +4^2 = 5^2

9+16=25

25=25

Three side lengths that will not form a triangle

1,2 9

The sum of the two smaller sides must be greater then the third

Answer:

probability of left handed female is

$\frac{31}{140}$

Step-by-step explanation:

you have 140 employees, and we know 65 employees are male. to work out how many female employees we minus 65 from 140 to get 75 female employees

$140 - 65 = 75$

we are told 31 females are left hand, to work out how many female are right handed we do 75-31 which equals 44 right handed females

$75 - 31 = 44$

if 90 of the total employees are right handed, and 44 females are right handed, in order to find how many males are right handed we do 90-44 which gives us 46 right handed males

$90 - 44 = 46$

to workout how many males are left handed, since we have 65 makes and 46 are right handed, just go 65-46 which gives us 19 left handed males

$65 - 46 = 19$

in order to find the probability of choosing a left handed female out if 140 employees, since we know there are only 31 left handed females out of 140 employees we just go

$\frac{31}{140}$
