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
Answer:
x=1/3
Step-by-step explanation:
