Question

If the probability of guessing an un correct answer is x/6 and guessing correct is 1/3 then the value of x
a) 4 b) 3 c) 1 d) 2

Answer 1

Answer:

answer is 4.

Step-by-step explanation:

As we know that adding all events gives us 1,

P(Event) + P (not an Event) = 1.

P(guessing the correct answer) + P(Not guessing the correct answer) = 1

1/3+x/6 =1

(2+x)/6=1

2+x=6

x=6-2

therefore,x=4
