You read the first 100 words in a book. You randomly pick one of them. What is the probability the word starts with a vowel and has more than four letters?
are the letters of the words in the book random?
yes
are you really sure this is the full question? seems to have some important details misisng
Now that you say so, they directions are read the first 100 words in a book. count the number of words that satisfy each of the events below. so i just count how many or do i have to generate a probabilty of assumed words? it seem too simple.
or do i do 1/100 * 5/26 * ? = probability?
*Facepalm* Now I see. Just take an example and count....
1/100 is the probability that a word is something...
is that your probability the first word is four letters?
I believe the directions are for example take ten words: The cat jumped over the moon and ran far away. (three begin with vowels and one is over four words)
So lets say i did that and they are both independent, how would i generate a probability from that?
i honestly cannot imagine this
3/10*1/10= the probability?
what is 10 for?
the 10 words
is that sentence included in the question?
This is an example im using to help you imagine it. 10 words instead of 100.
but is the sentence included in the question?
no.
then you can't and shouldn't use that
The diretions are to read 100 words but im giving you 10 words instead in order to understand the formula needed for when i do the 100 words.
you just picked random words...that shouldn't represent the 100 words
Yes, I know that it would'nt represent it propery. But let's say I already ready those 100 words and 40/100 of them are vowel and another 50/100 are over four words. MY QUESTION IS: What do I do once I get that information??
oh. you should'be said that clearly from the start...
multiply 50/100 and 40/100
remember if it says *and* you multiply... if it's *or* you add in your case.. first letter is vowel *and* four letters
OH! So or=add and and=multiply!!!! THANK YOU.
