Level: 
C
Two different dices (a white dice and a black dice) are rolled. The sum of the numbers on both dices is \(8\). Find the probability that there is \(4\) on the black dice.
\(\frac{1} {5}=0{.}2\)
\(\frac{1} {4}=0{.}25\)
\(\frac{6} {36}\doteq 0{.}1667\)
\(\frac{11} {36}\doteq 0{.}3056\)

Level: 
B
Two dices are rolled. Find the probability that we get either the same number on both dices or the sum of the numbers on both dices is \(6\).
\(\frac{10} {36}\doteq 0{.}2778\)
\(\frac{11} {36}\doteq 0{.}3056\)
\(\frac{6} {36}\doteq 0{.}1667\)
\(\frac{5} {36}\doteq 0{.}1389\)

Level: 
C
Two different dices (a white dice and a black dice) are rolled. We get the sum of the numbers on both dices \(6\). Find the probability that there is an even number on the black dice.
\(\frac{2} {5}=0{.}4\)
\(\frac{5} {36}\doteq 0{.}1389\)
\(\frac{5} {18}\doteq 0{.}2778\)
\(\frac{13} {36}\doteq 0{.}3611\)

Level: 
B
Two dices are rolled. Find the probability that we get either at least one number \(6\) or the sum of the numbers on both dices is \(8\).
\(\frac{14} {36}\doteq 0{.}3889\)
\(\frac{16} {36}\doteq 0{.}4444\)
\(\frac{11} {36}\doteq 0{.}3056\)
\(\frac{5} {36}\doteq 0{.}1389\)
