It's a conditional probability

P( getting a given number AND getting again the same number)


P(of getting any number) =1/6
P(of getting once again the same number) 1/6 x 1/6 = 1/36

Since these probabilities are independent of each other you would mulitiply the individual probabilities.
First Roll: P(1) = 1/6
Second Roll: P(1) = 1/6
(1/6) * (1/6) = 1/36

Give an example of a set of data displayed in a line graph
bazaltina [42]
Normally it’s like a ratio or starts with a graph on the side so you know what goes onto what part for example if you have a line graph you have 2 numbers.. so the y axis could be days and the x axis could be animals... so the graph would be showing how many animals per day... so it could be written out as 3:4 3,4 or how ever your teacher has you wrote them.. so then you would go on the X axis and find the 3 then go up 4 on the y axis and put a dot right at that point.
