# One three

We throw two dice. What is the probability that max one three falls?

Result

p =  0.972

#### Solution:

$p=\dfrac{ 6 \cdot \ 6-1 }{ 6 \cdot \ 6 }=\dfrac{ 35 }{ 36 } \doteq 0.9722 \doteq 0.972$ Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
