1) how many letter are there in the word paris?
1 2 3 4 5 P A R I S 5 Letters
good. how many of them are vowels?
A I 2 Vowels
good. so, probability of getting a vowel = (number of vowels) / (total number of letters) = ?
For sure D is not the answer right?
no. answer = number of vowels / total number of letters
So, The answer is letter 2/5?
yep
Yay...
Q 2) how many lolipops in all ?
They are 24 Lollipops In Total
good. out of them how many orange ones?
Count how many orange are they ?
yep. its given.
OK
It says they are 7 oranges
good. so, when you pick a lolipop, the chances of it being orange is: \(7\over 24\) now we are left with 23 lolipops out of which 6 are orange the chance of picking up another orange lolipop = \(6\over 23\)
so, to have both the lolipop, your chances are: \[{7\over24}\times {6\over 23}=?\]
