Answer 1

The probability he won on his first roll is 1/6.

Answer 2

Answer:

Bob has 16.67% of winning the game at his first roll.

Step-by-step explanation:

According to the problem, they are playing with a simple dice, which means it has 6 possible outcomes 1, 2, 3, 4, 5 and 6.

The one that gets 6 wins.

To find the probability of winning the first Bob's roll, we just need to find the simple probability of getting 6, which is

$P=\frac{1}{6}$

Therefore, Bob has 16.67% of winning the game at his first roll.
