Using the probability concept, it is found that:

  • There is a 0.1545 = 15.45% experimental probability of the name Karen being chosen.
  • There is a 0.125 = 12.5% theoretical probability of the name Karen being chosen.
  • If the number of names in the hat was different, the total number of outcomes would for the theoretical probability would be different, hence with less names the probabilities would increase, with more names the probabilities would decrease.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

For the experimental probability, the numbers of outcomes are taken from previous trials, hence considering the name Karen was chosen 19 times out of 123, we have that:

p_E = \frac{19}{123} = 0.1545

For the theoretical probability, the number of outcomes are taken from the "theory", that is, before the trials, hence considering that Karen is one out of 8 names:

p_T = \frac{1}{8} = 0.125

If the number of names in the hat was different, the total number of outcomes would for the theoretical probability would be different, hence with less names the probabilities would increase, with more names the probabilities would decrease.

How do you find the first five terms of a sequence defined recursively
Blizzard [7]
Interesting question. Good to know for computer science.
Suppose you have a function like 
an = 3x - 2 Try the first couple
a1 = 3(1) - 2
a1 = 3 - 2
a1 = 1

a2 = 3(2) - 2
a2 = 6 - 2
a2 = 4 So each term differs by 3
a2 - a1 = 3

an = a_(n - 1) + 3
a3 = a2 + 3
a3 = 4 + 3 
a3 = 7

a4 = a3 + 3
a4 = 7 + 3
a4 = 10

a5 = a4+ 3
a5 = 10 + 3
a5 = 13

I'll do one more and then check it.
a6 = a5 + 3
a6 = 13 + 3
a6 = 16

a6 = 3x -2
a6 = 3*6 - 2
a6 = 18 - 2
a6 = 16 which checks.

So the general formula is
an = a_(n - 1) * k if you were multiplying or
an = a_(n - 1) + k if you were adding. The key thing is that you are working with the previous term.

There are some books on a shelf and 12 are cookbooks. If 20% are cookbooks, how many books are on the shelf
GuDViN [60]
If u take 12 divided by .20 you would get 60 because if u think of it as a dinner bill say it is $60.00 and I want to give a 10% tip it would be $6 but if u give a 20% tip u would give $12
