Posted by on .

a box contains 100 cards, of which 25 are numbered 1, 35 are numbered 2, 30 are numbered 3, 10 are numbered 4. One card will be drawn from the box and its number X observed. Give the probability distribution of X

How in the world do I do this?
do I have to manually get the probabilites or is there a forumla I can use?

nevermind I don't need help.

  • stats - ,

    First make a table of probabilties.

    P(x=1) = 0.2
    P(x=2) = 0.35
    P(x=3) = 0.30
    P(x=4) = 0.15

    Now do a distribution plot, which is the likelihood of one of the four card types being drawn. P on y, x on x-axis etc.
