Question

Non Occurance of any event is 3:4. What is the probability of Occurance of this event?

Answer 1

Answer:

probability of Occurrence of this event = $\frac {1}{4}$

Step-by-step explanation:

Non occurrence = 3:4

Non occurrence = $\frac {3}{4}$

Probability of Occurrence + non-Occurrence = 1

Hence Probability of

Occurrence = 1 - non occurrence

Occurrence  = 1  -  $\frac {3}{4}$

Occurrence  = $\frac {4-3}{4}$

Occurrence  = $\frac {1}{4}$

probability of Occurrence of this event = $\frac {1}{4}$

Answer 2

Answer:

right answer is 4/7
