Question

a letter is chosen at random from the word probability find the probability that it is a vowel

Answer 1

Answer:

4/11

Step-by-step explanation:

a letter is chosen at random from the word probability find the probability that it is a vowel

Probability has letters

p , r , o , b , a , b , i , l , i , t , y

Total - 11 Letters

vowels are  a , e , i  , o u

so vowels in probability

o , a , i , i

Total - 4 Vowels

Probability = Favorable outcome/Total

Favorable out come = 4

Total = 11

=> probability of choosing Vowel  =   4 / 11

$\sf\textsf{Probability and statistics only.}$

$\huge\mathbb{\underline{Answer:-}}$

$\sf{The\: word \:given\: here\: is\: {\boxed{\star{\bold{\underline{P \:R \:O \:B \:A \:B\: I\: L\: I \:T \:Y}}}}}}$

$\sf{The \:vowels \:are\: {\bold{A,\:E,\:I,\:O,\:U.}}}$

$\sf\textsf{The vowels in the given word are (favourable outcomes) O, A, I, I (4)}$

$\sf\textsf{The total number of letters in the given word (total outcomes)=11}$

$\sf{We\: know\: that\: probability=\: {\boxed{\boxed{\star{\bold{\underline{Total \:outcomes/favourable\: outcomes}}}}}}}$

$\sf{Therefore, probability= {\boxed{\star{\bold{\underline{4/11}}}}}}$

$\sf\textsf{1) Probability is the mathematical concept of chance.}$

$\sf\textsf{2) Here, there is no absolute certainty.}$

$\sf\textsf{3) Words like may be, may not be etc, appropriately describe this concept.}$

$\sf\textsf{4) We calculate probability on the basis of some data only.}$

$\sf\textsf{5) If no data is there, then probability can't be calculated.}$

$\sf\textsf{6) Probability is related to the statistical and analysis part of mathematics.}$
