Answer:

4/5

Step-by-step explanation:

Given that:

Number of options = a, b, c, d, e

Number of correct answer choice = 1

Therefore, number of wrong answers = 4

Recall :

Probability = (number required outcome / number of total possible outcomes)

P(wrong answer) :

Number of Required outcome = number of wrong answer choices = 4

Total answers = 5

Hence,

P(wrong answer) = 4 / 5 = 0.8

Answer:

7

Step-by-step explanation:

line in the middle is an angle bisector

14/6 = 21 / 3x - 12

first, cross multiply

14 (3x - 12) = 6*21

Remove the brackets

42x - 168 = 126

Add 168 to both sides

42x = 168 + 126

Combine

42x = 294

Divide by 42

x = 294/42

x = 7
