Question

The probability of an event k is
  1. 0P(k)1
  2. 0P(k)1
  3. 0>P(k)>1
  4. 0<P(k)<1

A
0P(k)1
B
0>P(k)>1
C
0<P(k)<1
D
0P(k)1
Solution
Verified by Toppr

Let k be an event and n(k) be the number of elements of event k.
Now, total probability is 1
Then P(k)=No. of elements in sample spacen(k)1
And we know that, probability of an event can't be negative. So, P(k)0
Hence, 0P(k)1.
