Hi,
Problem 1:
A random variable X is uniform [0,1]. Find the probability that X's 2nd digit is 3.
As far as I understood, I need to find the probability of interval 0.03 - 0.04? And also all intervals that have 3 in 2nd digit? Like:
0.03 - 0.04
0.13 - 0.14
0.23 - 0.24
0.33 - 0.34
0.43 - 0.44
0.53 - 0.64
0.63 - 0.64
0.73 - 0.74
0.83 - 0.84
0.93 - 0.94
And then add the probability of each interval? Could someone help me, please?
Problem 2:
A random variable X is uniform [0,3]. Find the probability that X's first and/or second digit is 2.
I actually don't know how to tackle this problem. Could somebody point out what should I do with this? I don't expect to get the straight answer, just to show what I need to do. Somehow ended up being in class with calculus. Many thanks in advance.
