Question

The probability of guessing the correct
answer to certain test question is x/2
. If the probability of not guessing the correct answer to this question is
2/3, then find the value of x.​

Answer 1

Answer:

X=2/3

Step-by-step explanation:

if we add all the probability of an event we will get 1 as the answer.

X/2 + 2/3 = 1

(3x + 4)/6 = 1

3x +4 = 1×6

3x = 6-4

3x = 2

X = 2/3
