MAT 232 WEEK 2 FULLY SOLVED ASSIGNMENT
PAPER GRADED A+
◉ To find probability, blank the number of outcomes which satisfy
the event by the number of outcomes in the sample space.
Answer: Divide
◉ Example:
What is the probability of getting an even number when you throw
the die one time?
What happens if the number of die increases to two? Does this still
qualify as a classical probability experiment.
Answer: 1/2 or 0.50
No. Rolling two dice instead of just one results in a sample space
where the outcomes are not all equally likely
◉ Probabilities based on evidence (data) that have been observed
are called blank. Can be though of relative frequencies..
Answer: Empirical probabilities
,◉ If we toss a coin one time that is a classical experiment. If we toss
a coin 25 times and count the number of heads, then we have blank
evidence about the pro imita a head will be observed using this coin.
In the long run the probability will approach the theoretical value of
0.500 by the blank.
Answer: Empirical
law of large numbers
◉ Example: an insurance agent currently insures 192 teenage
drivers. Last year, 24 of those drivers had to file a claim for an
accident. Given this info what is the probability that in a given year a
teenager will have to file an insurance claim?.
Answer: 0.125
◉ A blank random variable is a random variable whose values are
always just countable values.
Answer: Discrete
◉ ??? A blank random variable is a.
Answer: Continuous
,◉ A blank variable is a numerical measure of the outcome of a
probability experiment, so it's value is determined by chance.
Answer: Random
◉ Discrete or continuous ?
Number of As on a math test
Number of cars in McDonald's drive thru for an hour
The speed of the next car that passes a state trooper.
Answer: Discrete
Discrete
Continuous
◉ ???An experiment is considered a binomial experiment if:
1) the experiment is performed a blank number of times(trials)
2) the trials are blank. This means the occurrence of one trial does
not affect the occurrence of other trials..
, Answer: Fixed
◉ ***Find the relative probabilities for the following data answer
choices on a SAT exam:
Choice. Frequency. Relative frequency
A. 19
B. 38
C. 74
D. 69
If a question were selected at random what is the probability the
correct answer choice was a C?
What is the probability it was an A or a B?.
Answer: Relative frequency:
A .095
B .190
C .370
D .345
◉ With the addition rules we blank probabilities of events together
