1 is not true generally, while 3 and 4 are never true. 2 is the only generally true conjecture.
Answer:
Step-by-step explanation:
Whenever a magnetic field linked to loop changes, the current is induced in the loop which sequentially opposes the cause of change in magnetic flux. So whenever the magnet moves towards and away from the loop then it causes the current to induce in the loop to oppose the change in magnetic flux by effectively creating a similar pole that is coming towards the loop.
For example, if the magnet north pole is coming towards loops then it effectively creates a north pole in front of the magnet.
So flow of current will glow the light bulb.

Answer:
P(X = 4) = 0.1876
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
In this question:

We want P(X = 4). So
