Contingency problem practice.

Bayesian contingency practice.

Frequency and relative frequency.

Using RANDI(1,10) on the TI-30XIIs a number of times, I get these frequencies. Find n and the relative frequencies, written as exact decimals.

f(1) = 7
f(2) = 7
f(3) = 6
f(4) = 6
f(5) = 3
f(6) = 2
f(7) = 5
f(8) = 5
f(9) = 6
f(10) = 3
