Question

On school swimming day Roger swims in the 50m, 100m and 200m
Freestyle races. Roger estimates that he has equal chances of
winning or losing each race. What is the probability that he wins at
least two races?

Answer 1

Step-by-step explanation:

When the cell is being charged, the anode becomes the positive (+) and the cathode the negative (−) electrode. This is also the case in an electrolytic cell. When the cell is being discharged, it behaves like a primary cell, with the anode as the negative and the cathode as the positive electrode.
