The probability of guessing the correct answer to a certain question is x/3.If the probability ofnot guessing the correct answer is 5x/3, then find the value of x. plz meritnation experts help me tomorrow is my exam

we know that, sum of the probability of any event is 1
so, probability of guessing correct ans + probability of not guessing correct ans = 1
i.e  x/3 + 5x/3 = 1
i.e. 6x/3 = 1
i.e. x = 1/2
therefore the value of x is 1/2
all the best for your exam...

x/ 3 + 5x / 3 = 1
6x/3 = 1
2x  / 3 = 1
2x = 3 
x = 3/2 = 1.5

The probaility of guessing the correct question is x/5. If the probability of not guessing the correct answer is 2x/3 then find the value of x

Probability of getting correct answer =x/2 Probability of getting not correct answer=2/3 We know that p(n1)+p(n2)..=1 Therefore 1-2/3=1/3 Nowx/2=2/3 3x=2(by cross mulplications) x=2/3(answer)

THE SUM OF PROBABILITIES OF ANY EVENT IS ALWAYS 1.
SO,PROBABILITY OF GETTING+NOT GETTING=1
x/3+5x/3=1
6x/3=1
6x=3
x=3/6=1/2

therefore value of x=1/2.

I want to ask 1 que.if guessing the correst answere to certain queation is x by 3 and not guessing the answere is x by 5 then,find value of x plzzzz fast tommorow is my exam.....

Sum of any probabilites = 1
here they are given to be x/3 and 5x/3

x/3 + 5x/3 = 1 
6x/3 = 1
6x = 1 x 3
6x = 3
x = 3/6
x = 1/2
x = 0.5

I know i'm two years late, but this may help someone else :)

No. Of total outcomes=x+y+z No. Of favourable outcomes=z P(E)=z/x+y+z

No, nearer to 1upon 2

sum of probability of any event=1 
    probability of guessing the correct answer+the probability of not guessing the correct answer=1
      =  x/3 +5x/3 = 1
         6x/3=1
         6x = 3*1
           x = 3/6
             x=1/2 or 0.5

   therefore the ans = 1/2 or 0.5
