In a throw of a dice the probability of getting one in even number of throw is
Explanation for the correct option:
Step 1: Determining the probability of one in an even number of throw
The probability of getting one in the second throw = =
The probability of getting one in the fourth row ==
The probability of getting one in the sixth row ==
Hence, the required probability =
=
=
Step 2: Applying the concept of infinite geometric series
So, the required probability =
Hence, the probability of getting one in an even number of throw
Therefore, the correct option is (B)
