At a Covid testing center, data shows that 12.3% of people
getting tested have the virus (i.e., test is positive). Based on
this data, what is the probability that they next 3 people tested
will all be positive? (note: provide your answer in decimal form,
rounded to 3 decimal places)
In a student club with 8 members they vote to select 3 officers.
How many different possible outcomes are there? (note: Since each
position is unique, even if the same people are selected as
officers, they could have different roles. In other words, order
matters so this is a permutation problem.)
In a student club with 13 members, they want to form a committee
consisting of 2 members. How many possible committee combinations
are possible? (note: Since each committee member has the same role,
the sequence or order does not matter, and so this is a combination
problem.)
They look so easy but they're so complicated for some reason for
me any help is greatly appreciated thanks
