Question

please answer it guys please. it was so urgent guys​

Answer 1

Explanation:

12)a)there r 5 vowels in alphabets

so probability of getting an vowel is 5/26

b) there r 10 letters which come after P

so the probability of getting a letter after P is 10/26=5/13

c)there are total 26 alphabets, 5 vowels and 21 consonants., in that way probability of getting vowels or consonants is 5/26 or 21/26

d)as we know there are 5 vowels

so probability of not getting an vowel is 21/26

NEXT SUM:

BX=1/2AB and BY=1/2BC

by the above two measurements we can understand that BX and BY are the midpoints of AB and BC .

so as given in the question AB=BC

as those Two lines are equal., then their midpoints are also equal

BX=BY

Hence proved

NEXT SUM:

13) answer is above .....

hope this helps you
