It's desired to model the random variable X with a shape that rises to a peak near x=6 and whose possible values are integers 1-6. Copy paste the following lines of code into R: x <- 1:10 shape <- x*(12-x) barplot(shape, names.argex) This "shape" isn't a valid PMF because the numbers don't sum to 1. Convert the numbers in "shape" to valid probabilities and report P(X-5). Copy/paste all digits from R into your answer here.

Question
It's desired to model the random variable X with a shape that rises to a peak near x=6 and whose
possible values are integers 1-6.
Copy paste the following lines of code into R:
x <- 1:10
shape <- x*(12-x)
barplot(shape, names. arg=x)
This "shape" isn't a valid PMF because the numbers don't sum to 1. Convert the numbers in "shape"
to valid probabilities and report P(X-5). Copy/paste all digits from R into your answer here.
