Number of tiles required=500ft²÷1ft²=500
D because it is 2 elements combined
<span>Total constants = 15
Total vowels = 21
Total letters = 15 + 21 = 36
Probability of a consonant on first place = 15/36
Probability of a vowel on second place = 21/36
Probability of getting a consonant and then a vowel (or vice-versa):
(15/36)(21/36) = 315/1296 = 35/144
