Question

Find the probability of an event that mobile number does not contain Zero ?​

Answer 1

Answer:

Technically, if PB=0 , then P(A|B) is undefined. However, in applied probability, one conditions on a continuous random variable’s taking on a specific value all the time. For example, one may speak of P(Y≤y|X=x) when X and Y are bivariate normal. Also, in Bayesian statistics, one may treat the unknown parameter π of a Bernoulli random variable I as a continuous (e.g., beta) random variable and say P(I=1|π=p)=p .

In applied probability, we make such approximations using density functions. Somewhat advanced measure theory is needed to approach this concept formally.

Answer 2

Answer: 0

Step-by-step explanation:

Basically all mobile numbers have 0 as a digit as a prefix.

So, it's a null set (Doesn't have any elements)

P(∅)=0
