Answer 1

Answer:

D 4/121

C 14/55

Step-by-step explanation:

The total number of tiles in mathematics is 11

P(a) = number of a's/ total = 2/11

We replace the tile

so there are 11 tiles and the are mathematics

P(a) = number of a's/ total = 2/11

P(a, replace then a) = 2/11 *2/11 = 4/121

P(vowel) = vowel/total = 4/11

We keep the vowel so there are only 10 tiles

3 vowels and 7 consonants

P( consonants) =  consonant/total = 7/10

P(vowel, no replace, consonant) = 4/11*7/10 = 14/55
