The correct answer is - 6.25 mAh.
Explanation:
According to the Ohms law of power, the current of a source can be found with the help of the formula
I = V ÷ R
where, I (amps) = V (volts) ÷ R (Ω)
By placing the value given:
I = 5.00/800
I = 6.25 mAh
The current output of the charger would be 6.25 mAh

Option: A and D are the correct answer.
A. 50% and D. 25%
Explanation:
We know that the probability of an event is the chance of occurring of an event.
The probability of an event always lie between 0 and 1.
It is equal to zero if the event will never occur and is equal to 1 if the event is certain to occur.
Also, the probability could be in ratio or it could be in percentage and the percent may be between 0%-100%
Hence, in the given options:
B) 557 is incorrect as the probability is greater than 1.
c) 1×104=104 is incorrect since the probability is greater than 1
Hence, the correct options are:
A. 50%
and D. 25%
