उत्तर
a. We can clearly see that all the 5 letters are vowels, i.e. A, E, I, O.
Hence, it is certain to draw a vowel, i.e. probability of drawing a vowel is 1.
b. Probability = `"Number of cards marked U"/"Total number of cards" = 1/5`
c. Probability = `"Number of cards marked A or I"/"Total number of cards" = 2/5`
d. Probability = `"Number of cards marked with a consonant"/"Total number of cards" = 0/5 = 0`
Hence, it is impossible to draw a consonant.
