Question65%
of the people in Missouri pass the driver’s test on the first attempt. A group
of 7 people took the test. Which of the following equations correctly calculate
the probability that at least 3 in the group pass their driver’s tests in their

QuestionGive
the numerical value of the parameter p in the following binomial distribution
scenario.
A softball
pitcher has a 0.692 probability of throwing a strike for each pitch and a 0.308
probability of throwing a ball. If the softball pitcher throws 29 pitches, we
want to know the probability that more than 17 of them are strikes.
Consider
strikes as successes in the binomial distribution. Do not include p= in your
answer.
QuestionConsider
how the following scenario could be modeled with a binomial distribution, and
answer the question that follows.
54.4% of
tickets sold to a movie are sold with a popcorn coupon, and 45.6% are not. You
want to calculate the probability of selling exactly 6 tickets with popcorn
coupons out of 10 total tickets (or 6successes in 10 trials).
What value
should you use for the parameter p?
QuestionGive
the numerical value of the parameter p in the following binomial distribution
scenario.
A softball
pitcher has a 0.721 probability of throwing a strike for each pitch and a 0.279
probability of throwing a ball. If the softball pitcher throws 19 pitches, we
want to know the probability that more than 15 of them are strikes.
Consider
strikes as successes in the binomial distribution. Do not include p= in your
answer.
QuestionGive
the numerical value of the parameter n in the following binomial distribution
scenario.
The
probability of buying a movie ticket with a popcorn coupon is 0.597 and without
a popcorn coupon is 0.403. If you buy 18 movie tickets, we want to know the
probability that no more than 13 of the tickets have popcorn coupons.
Consider
tickets with popcorn coupons as successes in the binomial distribution. Do not
include n=in your answer.
