What's inside
- X is a continuous random variable with pdf f(x) = 3x^2/125 for 0 <= x <= 5, and f(x) = 0 otherwise. State P(X = 5) exactly, and explain why.
- Find the constant k so that f(x) = kx^2 for 0 <= x <= 2 (and f(x) = 0 otherwise) is a valid probability density function.
- Show that f(x) = 2x/25 for 0 <= x <= 5, and f(x) = 0 otherwise is a valid probability density function by checking f(x) >= 0 and integrating over its support.
- Find the constant k so that f(x) = k for 2 <= x <= 5 (and f(x) = 0 otherwise) is a valid probability density function.
- Show that f(x) = 3x^2/64 for 0 <= x <= 4, and f(x) = 0 otherwise is a valid probability density function by checking f(x) >= 0 and integrating over its support.
- Find the constant k so that f(x) = kx for 0 <= x <= 3 (and f(x) = 0 otherwise) is a valid probability density function.

Frequently asked questions
Are these statistics worksheets free?
Yes. Every worksheet on ChalkBee is free to view and print or save as a PDF, with no login required, and the answer key is free too. Pro removes the watermark and adds differentiated sets, worksheet packs and unlimited custom generation.
Do the worksheets have answer keys?
Yes, free, on every sheet. The answers are computed in code from the exact questions on the page, and the key prints on a page of its own so the student sheet stays clean.
What grades do statistics worksheets cover?
Statistics worksheets on this page cover Probability & Statistics. There are 1 printable sets in total, grouped by grade so you can pick the right level.
How do I print or download them?
Open any set, then use your browser's print option to print it or to save it as a PDF. The pages are laid out to print cleanly on standard letter or A4 paper.
