Question

(3) If the probability of occurence of event A is x/2
and the probability of non-
occurence of event A is 2/3 then x =​

Answer 1

Step-by-step explanation:

x/2 + 2/3=1

x/2=1/3

x=2/3

Answer 2

probability of occurrence of an event + probability of non-occurrence of the event =1

so,

x/2+2/3=1

x/2=1-2/3

x/2=1/3

x=2/3

therefore the probability of non-occurrence of the event =2/3
