Answer:
A. 6
B. 1/3
Step-by-step explanation:
A. Each dice has 3 different scores: 0,1,6
So there will be 6 different total scores: 0 (=0+0) , 1 (=0+1) , 6 (=0+6) , 2 (=1+1), 7 (=1+6) , 12 (=6+6).
B. To get a total of 7, you will need 1 and 6 from 2 dices.
Probability of getting 1 = 3/6 = 1/2
Probability of getting 6 = 2/6 = 1/3
Probability of getting 7 = (probability of getting 1 on dice 1) * (probability of getting 6 on dice 2) + (probability of getting 6 on dice 1) * (probability of getting 1 on dice 2) = 1/2 * 1/3 + 1/3 * 1/2 = 1/3
