Sagot :

Answer:

0.583333333333

Step-by-step explanation:

we have 9 letters

3 vowels: A , E , I

6 consonant: B, C, D, F, G , H

Consider the event V : «choosing at least 1 vowel»

[tex]\Longrightarrow \overline{V} \ \colon \ \text{choosing 2 consonant}[/tex]

[tex]p(V) =1-p\left( \overline{V} \right) =1-\frac{C^{2}_{6}}{C^{2}_{9}}=0.583333333333[/tex]
