Question

12. What is the probablity of obtaining a number higher than 4 when rolling a dice?

13.

a. What is the probability of obtaining a total of 10 or 12 when launching 2 dice at the same time (adding total of both dices)?

b. ¿Does it change if you add a 3rd dice? How?

14) What would be the probability of obtaining a total of 2 if you roll 3 dice at the same time?

Answer 1

12) Probability of obtaining number higher than 4 when one dice roll =2/6 =0.33

13) a. Probability of obtaining total 10 or 12 when two dice roll=4/36 =0.11

13 b) Probability of obtaining 10 or 12 when 3 dice roll =52/216=0.241

Probability of obtaining 10 or 12 when 3 dice roll is different from the two dice roll because sample space changed when 3 dice roll.

14) Probability of obtaining a total 2 when three dice rolls is zero (0) because minimum sum can be 3
