Total = 11

2/11 × 1/11 × 4/10

Answer 2

Answer:

A  4/605

Step-by-step explanation:

mathematics = 11 letters

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

we replace it so we have  mathematics = 11 letters

P(s) = number of s's/total = 1/11

not replacing it

we replace it so we have  mathematic = 10 letters

P(vowel) = number of vowel/total = 4/10 = 2/5

P(m, replace,s, no replace, vowel) = 2/11*  1/11 * 2/5 =  4/605
