Answer:
0.1 or 10%
Step-by-step explanation:
[tex]\begin{array}{cc}outcome&probability\\1&0.1\\2&0.2\\3&0.3\\4&0.2\\5&x\\6&0.1\end{array}[/tex]
The sum of the probabilities of all possible outcomes must equal 1. Therefore, the probability of rolling a five, which is the only unknown probability, can be determined as:
[tex]0.1+0.2+0.3+0.2+x+0.1 = 1\\x=0.1[/tex]
The probability of rolling a 5 is 0.1 or 10%.
