Question

jar n ( A)= 2 p (A) =1/5 tar n (s) =?
​

Answer 1

Answer:

10

Step-by-step explanation:

p(a)=n(a)/n(s)

1/5=2/n(s)

=n(s)=10

Answer 2

Given that n ( A)= 2, p (A) =1/5, find n (s) :

Explanation:

• Probability of A = No.of observations  of A/ No. of total observations
• P(A) = n(A)/ n(s)
• 1/5 = 2/n(s)
• n(s) = 10
• 10 is the answer.
