00:01 Hey there, welcome to numerade.

00:03 We are looking at an experiment here that was conducted on two dice.

00:09 These two dice were thrown 100 times and the sum showing on the dice is being recorded.

00:18 So the frequency histogram is shown on to the right hand side.

00:23 So we're going to start with part 8.

00:27 What was the most frequent outcome of the experiment? so what we're looking for here is the highest frequency.

00:40 So with the highest frequency bar here, we can see we have nine.

00:51 Part b, we're looking for the least frequent, so the lowest frequency.

01:06 So what we get for the lowest frequency here is 12, all the way in the right -hand side.

01:19 Part c, how many times did we observe an 8? so the frequency of 8, subscript 8 is equal to.

01:32 So what we have here is in between the two bars and which 8 is between 15 and 20.

01:43 So we have 15, 16, 17.

01:47 So 16 should be right below.

01:49 So let's make it as a 17.

01:57 All right.

01:58 And then, part d.

02:00 How many more sevens were observed than fives.

02:06 So we're looking for the frequency of seven minus the frequency of five.

02:13 So the frequency of seven here is, so 10, 11, 12.

02:25 Let's see what we have here.

02:26 So that was 8.

02:28 Eight was over here...
