Question

Each letter of the word "mathematics" is written on a separate piece of paper and put into a bag. you are asked to pick a random letter from that bag without looking. what is the probability that you pick a vowel

Answer 1

M,t,h,c,s are all consonants. "Mathematics" has 11 letters and 7 of them are consonants and the other 4 are vowels. 100%/11 = 9.091. 9.091 x 4 = 36.36. So, there is a 36.36 % (4/11) chance that you will pick a vowel and a 63.64 % (7/11) chance that you will pick a consonant. 

I hope that helps!!!
