@ParthKohli help

Answer 3

All right. Let's start with the easiest ones.

What is the probability that a letter in his name pops up? Add your thoughts.

Answer 4

There are three letters in his name, {e,l,i}
There are twenty-six letters in the alphabet, which I don't have the patience to type all of lol

Answer 5

1/26 is the probability of one letter... right

Answer 6

yes.

Answer 7

how about three letters?

Answer 8

3/26

Answer 9

there you go.

Answer 10

how about a letter in his name OR S? hint: we are rooting for {e,l,i,s} that is four letters

Answer 11

4/26

Answer 12

there you go again. simplify the fraction.

Answer 13

divide by 2 = 2/13

Answer 14

yes!

can you see where this is going? can you try to do the rest of the two? i'm supporting you =)

Answer 15

ok let me try

Answer 16

so a vowel in his name
e,i...... so 2/26

Answer 17

very good!

Answer 18

but thats not in the options.... do i simplify?

Answer 19

exactly.

Answer 20

answer: 1/13

Answer 21

yup

Answer 22

a letter in his name or consonant
3/26 ...eli

Answer 23

or consonant... so a lot of letters like b, c, d... etc. qualify.

Answer 24

so 26-3

Answer 25

let's see.

a letter in his name or consonant.

there are 3 letters in the name and 21 consonants, so the total should be 24.

but because there is one letter common between both of them, we subtract one and end up with 23.

so correct.

Answer 26

so 23/26

Answer 27

anyway, that was the only option left so we can choose that without a doubt. :P

Answer 28

yup.

Answer 29

omg... thankyou for helping me!!!

Answer 30
