Probability Of Guessing The Correct Answer = x/3
Probability of Not Guessing The Wrong Answer = 1 - x/3 --- to test this
x / 5 = 1 -x/3 take example
x/5 = (3 - x) / 3 of 1 coin tossed
3x = 5(3 - x) in air and let assume
3x = 15 - 5x P of getting tail is
3x + 5x = 15 25% so P of getting
8x = 15 Head is 1 - 25%
x = 15/8 which is 75%
Value Of X is 15/8

Answer: x=1/2
Step-by-step explanation:p(E)=x/3
p(not E)=5X/3
P(E)+p(not E)=1
then,
x/3+5x/3=1
6x/3=1
x=1/2
