100
the probability of rolling a 2 (give answer as a fraction)
1/6
100
This probability is the likelihood that something would occur compared to the total number of possible outcomes. It is what would be expected to occur.
Theoretical Probability
100
There are 3 blue, 2 green and 4 yellow tiles in a dish. If I draw one and replace it, then draw another what is the probability of drawing two blues.
1/9
