Question 1102035: The probability that when a drawing pin is tossed in the air it lands with point facing up 'point up' is 1/4 and that it lands with point facing down 'point down' is 3/4
This drawing pin is tossed twice and X is the random variable that counts the number of times it lands 'point up'. Draw a histogram to represent the probability distribution in Question 1 above and shade the area representing the probability for X=0
The answer i got for Q1 was P(X=x)
x=0 9/16
x=1 6/16
x=2 1/16
Im so confused because I thought histograms were for continuous data? If someone can show me what the histogram is supposed to look like that would be amazing.

The answer i got for Q1 was P(X=x)
x=0 9/16 = 9/16
x=1 6/16 = 22/16
x=2 1/16 = 33/16
----------
Horizon axis has 0 , 1, and 2
Vertical axis is 16ths and has columns
The histogram has 3 columns 0 to 1; 1 to 2, 2 to 3 are the three bases
The columns are 9 , 22, and 33 high
