Question

Give the numerical value of the parameter *p* in the
following binomial distribution scenario.

A softball pitcher has a 0.675 probability of throwing a strike for
each pitch and a 0.325 probability of throwing a ball. If the
softball pitcher throws 29 pitches, we want to know the probability
that exactly 19 of them are strikes.

Consider strikes as successes in the binomial distribution. Do not
include *p*= in your answer.

Answer #1

Identify the parameter p in the following binomial distribution
scenario. The probability of buying a movie ticket with a popcorn
coupon is 0.699, and the probability of buying a movie ticket
without a popcorn coupon is 0.301. If you buy 24 movie tickets, we
want to know the probability that more than 16 of the tickets have
popcorn coupons. (Consider tickets with popcorn coupons as
successes in the binomial distribution.)

Identify the parameter p in the following binomial distribution
scenario. The probability of buying a movie ticket with a popcorn
coupon is 0.676 , and the probability of buying a movie ticket
without a popcorn coupon is 0.324 . If you buy 25 movie tickets, we
want to know the probability that more than 16 of the tickets have
popcorn coupons. (Consider tickets with popcorn coupons as
successes in the binomial distribution.)

Identify the parameter p in the following binomial distribution
scenario. The probability of buying a movie ticket with a popcorn
coupon is 0.787, and the probability of buying a movie ticket
without a popcorn coupon is 0.213. If you buy 20 movie tickets, we
want to know the probability that more than 13 of the tickets have
popcorn coupons. (Consider tickets with popcorn coupons as
successes in the binomial distribution.)

Identify the parameter p in the following binomial distribution
scenario. The probability of buying a movie ticket with a popcorn
coupon is 0.656 , and the probability of buying a movie ticket
without a popcorn coupon is 0.344 . If you buy 15 movie tickets, we
want to know the probability that more than 10 of the tickets have
popcorn coupons. (Consider tickets with popcorn coupons as
successes in the binomial distribution.)

Identify the parameter p in the following binomial
distribution scenario. The probability of buying a movie ticket
with a popcorn coupon is 0.690, and the probability of buying a
movie ticket without a popcorn coupon is 0.310. If you buy 20 movie
tickets, we want to know the probability that more than 13 of the
tickets have popcorn coupons. (Consider tickets with popcorn
coupons as successes in the binomial distribution.)

Consider a binomial probability distribution with p=.35 and n=7.
what is the probability of the following?
a. exactly three successes P(x=3)
b. less than three successes P(x<3)
c. five or more successes P(x>=5)
