Step-by-step explanation:
picking 3 consonants and 2 vowels when 5 letters are picked (without replacement) from a set of alphabet tiles.
There are 26 letters in alphabet
number of consonants = 21 and number of vowels = 5
We need to pick 3 consonants from 21 consonants
Probability of picking 1 consonant from 26 alphabets = 21/ 26
after picking 1 consonant then number of consonant becomes 20
Probability of picking second consonant from 25 alphabets = 20/ 25
Probability of picking third consonant from 24 alphabets = 19/ 24
We need to pick 2 vowels from 5 vowels
Probability of picking 1 vowel from remaining 23 alphabets = 5/ 23
Probability of picking second vowel from remaining 22 alphabets = 4/ 22
Now multiply all the probabilities

= 0.02022
You have 0.15 + 0.36 just like you would just add normal so 1. Would be 0.51 and the other one would be 0.15
Answer:

Answer: Infinite solutions
Step-by-step explanation: 3x -7 = 3(x-3)+2
3x + -7 = (3)(x) + (3)(-3) + 2
3x + -7 = 3x + -9 + 2
3x - 7 = (3x) + (-7)
3x -7 - 3x = 3x - 7 - 3x
-7 + 7 = -7 + 7
0 = 0
