Answer 1

Answer:

4/11

Step-by-step explanation:

a letter is choosen at random from the word

probability find her probability that it is a vowel

probability has letters

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

total 11 letters

a, e, i, o, u

so wovels in probability

o a I I

total 4 vowels

probability = favorable outcome /total

favorable outcome = 4

total 11

=> probability of choosing vowel = 4/11

ASSUMPTIONS

There are 4 vowels in “probability"

There are 11 letters (including vowels) in “probability".

P(A vowel is selected) = ( 4/11 ) = 0.3636364 =

36.36364% = 36.37% (rounded)

Note that P(Consonant Selected) =

= ( 7/11) = 0.6363636 = 63.63636% = 63.637% (rounded) or alternatively:

P(Consonant Selected) = [ 1 - P(Vowel Selected) ] = [ 1 - 36.37% ] = 63.63% as above.

SUMMARY

P(A Vowel is Selected) = ( 4/11 ) = 0.3636364 = 36.36364% = 36.37% (rounded)
