Hi, can someone check if i did this right?
1) Two dice are rolled. We only observe that there is at least on "six" showing. What is the probability that the sum of two dice is less than 12?
2) find the probability that a family has two boys given that the family has at least one boy.
3) two dice are rolled. if the two faces are different what is the probability that at least one is six?
thank you, coz my stats and maths skills arent so good
