myininaya (myininaya):
you need the sum of the probabilities to equal 1
that is you need
\[\frac{11}{20}+\frac{6}{20}+\frac{x}{20}=1 \\ \text{ and yes } 11+6=17 \\\ \frac{17+x}{20}=1\]
so what does x need to be ?
OpenStudy (anonymous):
i got 3 / 20
myininaya (myininaya):
that's right
Mehek (mehek14):
