Question

if a student probability of the right answer is x/12 and wrong answer probabilty is 1/2 from a question paper, then what is the value of X?​

Answer 1

Answer:

X=6

Step-by-step explanation:

Wrong probability+right probability=1

X/12 + 1/2 =1

(X+6)/12=1

X+6=12

X=6

Answer 2

X=6

X/12+1/2=1

X/12+6/12=1

X+6=1×12

X+6=12

X=12-6

X=6
