Theoretical Probability
A fair 6-sided die
Roll a fair 6-sided die and let $A$ be the event "rolling a 3".
$n\left(A\right)=$ .
$n\left(U\right)=$ .
The probability of rolling a 3 on a fair 6-sided die is (as a fraction) $P\left(A\right)=$ .
Let $B$ be the event "rolling an even number".
$n\left(B\right)=$ .
$n\left(U\right)=$ .
The probability of rolling an even number on a fair 6-sided die is (as a fraction) $P\left(A\right)=$ .A deck of cards
