Robin randomly selects a number between 1 and 20. What is the probability that the number selected is the square of a natural number?

OpenStudy (anonymous):

squared numbers between 1 &20 are1 ,4,9,16 favourable events=4 total no. of events=20 P=?

OpenStudy (anonymous):

?

OpenStudy (anonymous):

that makes no sense

OpenStudy (jennyrlz):

hmm let me try to clarify for you

OpenStudy (jennyrlz):

so he said that the squared numbers between 1 and 20 are 1,4,9,16

OpenStudy (jennyrlz):

that means that their are four possibilities, you still with me

OpenStudy (jennyrlz):

there*

OpenStudy (anonymous):

yea

OpenStudy (jennyrlz):

ok so there are a total of 20 possibilities

OpenStudy (jennyrlz):

so the chances of you getting a squared number are 4/20

OpenStudy (jennyrlz):

you get it :)

OpenStudy (anonymous):

yea but that isnt one of my choices

OpenStudy (jennyrlz):

well you can still simplify

OpenStudy (jennyrlz):

4/20 divide both sides by 4 1/5

OpenStudy (jennyrlz):

is that one of your choices :)

OpenStudy (anonymous):

yup
