Using figure 9-1, which pairing matches the structures shown in the cell diagrams with the processes that take place within those structures?

• a: photosynthesis; b: cellular respiration
• c: photosynthesis; d: cellular respiration
• d: photosynthesis; e: cellular respiration
• e: photosynthesis; d: cellular respiration

Step-by-step explanation:

The odds for an event is basically the ratio of the favorable outcomes to the unfavorable outcomes.

Given : The odds of choosing one black ball from an urn are 7 to 13.

i.e. favorable outcomes for getting black ball = 7

=7+13=20

Then, the probability of getting a black ball

Hence, the required probability
