Answer:
0.7
Explanation:
There is an addition of certain amount of T4 phage to a certain amount if bacterial cells, the purpose of these T4 phages were to replicate without the aid of the metabolic action of their host bacterium and so that they can used to treat bacterial infections as well.
Now, for example, if a single bacteria is infected with a single phage, and 0.3 did not have any phage bound. That typically implies that;
1 - 0.3 = 0.7
THUS, the ratio of initial average phage to bacteria ratio was 0.7 .
