Question

I have two fair dice. Each of the dice is numbered 1 to 6. (a) The probability that I will throw double 6 (both dice showing number 6) is 1 36 What is the probability that I will not throw double 6 ? p(not double 6) = (b) I throw both dice and get double 6. Then I throw both dice again. Which one answer from the list below describes the probability that I will throw double 6 this time? less than 1 36 1 36 more than 1 36 I start again and throw both dice. (c) What is the probability that I will throw double 3 (both dice showing number 3) ? p(double 3) = (d) What is the probability that I will throw a double? (It could be double 1 or double 2 or any other double.) p(double) = Question 13 On a road there are two sets of traffic lights. The traffic lights work independently. For each set of traffic lights, the probability that a driver will have to stop is 0.7. (a) A woman is going to drive along the road. (i) What is the probability that she will have to stop at both sets of traffic lights? (ii) What is the probability that she will have to stop at only one of the two sets of traffic lights? (b) In one year, a man drives 200 times along the road. Calculate an estimate of the number of times he drives through both sets of traffic lights without stopping.
