What is the probability of you selecting a vowel (A, E, I, O, U) and then, without returning it, selecting a consonant? Explain the steps to calculating this probability.

21/130

Step-by-step explanation:

26 letters in alphabet

- 5 vowels

- 21 consonants

P(vowel) = 5/26

With no replacement, there are now 25 letters of which 21 are consonants

P(consonant) = 21/25

Multiply the two probabilities fo get 21/130

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
