There are 6 possible outcomes when rolling a die: 1, 2, 3, 4, 5, 6
So, P(1 or 2) = 2/6 = 1/3
We want the probability of getting a 1 or a 2 on all three tosses
P(1 or a 2 on all three tosses) = P(1 or 2 on 1st toss AND 1 or 2 on 2nd toss AND 1 or 2 on 3rd toss)
= P(1 or 2 on 1st toss) x P(1 or 2 on 2nd toss) x P(1 or 2 on 3rd toss)
= 1/3 x 1/3 x 1/3
= 1/27
Answer: 1/27
Cheers,
Brent

Probability of getting 1 OR 2 first time: 1/6 + 1/6 = 2/6 = 1/3
Probability of getting 1 OR 2 second time: 1/6 + 1/6 = 2/6 = 1/3
Probability of getting 1 OR 2 third time: 1/6 + 1/6 = 2/6 = 1/3
Probability of getting 1 OR 2 1st AND 2nd AND 3rd time: 1/3 * 1/3 * 1/3 = 1/27
Please correct me if I am wrong.
