Question

The probability of guessing the correct answer is x/2 if the probability of not guessing the correct answer is 5x/2 find the value of x​

Answer 1

Answer:

P(occuring of an event) + P(Not occuring the event) = 1

Therefore , x/2 + 5x/2 = 1

== 3x = 1

== x = 1/3

Answer 2

x/2+5×/2=1(As total possible outcome of am event is)
