what is the equation for independent events, and what does independent events acc mean?
is this rule of equation for independence limited to only venn diagrams?

the outcome of one has no effect on the outcome of the other

this is not limited to venn diagrams. can be used in any question involved with probability

what does mutually exclusive mean and what equation is used for this

is this rule of equation for mutually exclusiveness limited to only venn diagrams?

this is not limited to venn diagrams. can be used in any question involved with probability

other than venn diagrams and tree diagrams, what can be used to calc probability

sample space diagrams e.g (if the question was on abt summing them)

what does mutually exclusive mean in terms of the venn diagram look?

they dont overlap

do this question

do these questions

do this question

he squared them, because he was using the independent formula. u can do this

and cuz the only way for this to work are:

X₁ = a, and X₂ = a (and so on and so forth) u can use the independent equation

do this question (dont do c)
