Answer 2

Given : The word P R O B A B I L I T Y .

$\dag\frak{\underline {As \:We\:know \:that\::}}$

• There are five vowels in Alphabets : A , E , I , O , U .

Now ,

• By Finding vowels in Given word P R O B A B I L I T Y .

As , We can see that ,

• There are four vowels in the word ( P R O B A B I L I T Y ) "( O , A , I , I )"

Therefore ,

• Favorable Outcome or The no. of Vowels is 4 .

• The number of Total Outcomes or The total number of word in ( P R O B A B I L I T Y ) is 11 .

$\dag\frak{\underline {As \:We\:know \:that\::}}$

$\star \boxed {\sf { \pink { Probability = \dfrac{Favorable \:Outcomes}{No.\:of\:Total \:Outcomes}}}}$

⠀⠀⠀⠀⠀⠀$\underline {\frak{\star\:Now \: By \: Substituting \: the \: Given \: Values \::}}$

Therefore, ⠀⠀⠀⠀⠀

• $\therefore {\underline{ \mathrm { Probability \:=\:\bf{\dfrac{4}{11}\: }}}}$⠀⠀⠀
