Which value for "a" completes the conditional relative frequency table by row?
irinina [24]

Answer:

a=0.1

Step-by-step explanation:

From the given frequency table, Fiction= Poetry+Prose=total

⇒0.2+0.8=1.0=total

And, Poetry+prose= total

⇒0.18+0.82=1.0= total

Thus, following the same path,we have

Non Fiction= Poetry+prose=Total

⇒a+0.9=1.0

⇒a=1.0-0.9

⇒a=0.1

Therefore, the value of a will be: 0.1
