okay.. what's your question?
is your cat not helping you? :X
Each of the letters in the word MATHEMATICS is represented by a letter tile in a bag. Stacey picks three letters, without replacement. To the nearest whole percent, which is the probability that she'll get all vowels? two percent three percent five percent six percent Question
my cat is still nuts
sorry.. i hate probability problems.. hehe. :D
how many vowels are there?
@amistre64 4 vowels..
4 vowels, how many letters total?
im assuming that the information is that there is that each letter in the word is a seperate tiles; and not just say one M tile to represent all the Ms
the bag contains M A T H E M A T I C S that is 11 letters out of which A E A I are vowels probability = what you desire / what is there
@amistre64 11 letters..
then we need to run thru "without replacement" 4/11 that leaves 3 out of 10 left 3/10 that leaves 2 out of 9 left 2/9 adding them up gives the probability they seek
i think I meant multiply, not add
:O i made a mistake
the probability of getting a vowel; and another vowel; and another vowel the "and" indicates multiplication off the 3 simple event probabilities
4*3*2 -------- 11*10*9
4/165 is the result in multiplying them out..
then are you suppose to turn into a decimal
that depends on how the person grading the assignments wants it to be formatted
4/165 is a suitable value between 0 and 1
so 2 percent
2.43% if any degree of accuracy is desired
or 2.42 ... depends on how you round it
Leander rolls a standard die twice. Which of the following compound events has the greatest chance of occurring? the probability of 2 and 2 the probability of 2 and 5 the probability of 5 and even the probability of even and even
