The probability of picking a red marble from a bag is 20%. what are the oddthe s in favor of picking a red marble?

20 % = 20/100 = 1/5

1 red marble out of 5 total marbles

1 red marble and 4 not red marbles

odds in favor  means number of favorable outcomes : number of unfavorable outcomes

this basically means  red marbles : not red marbles

                                   1: 4

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.
