MATH 225N Week 4 Assignment: Evaluating Probability with the Binomial Distribution
- Question: A weighted coin has a 0.596 probability of landing on heads if you toss the coin 12 time what is the probability of getting heads more than 7 times? ( Round your answer to three decimal places if necessary)
- 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 as 0.325 probability of throwing a ball if the softball pitcher throws 29 pitchers 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?
- Question: identify the parameter P in the following binomial distributions scenario the probability of winning an arcade game is 0.403 and the probability of losing is 0.5 97. if you play the arcade game 24 x we want to know the probability of winning more than 7 times (consider winning as a success in the Binomial Distribution)
- Question: a softball pitcher has a 0.67 to probability of throwing a strike for each page if the softball pitcher throws 15 pieces what is the probability that more than 9 of them are strikes round your answer to 3 decimal places?
- Question: give the numerical value of the parameter P in the following Binomial Distribution scenario the probability of buying a movie ticket with the Popcorn coupon is 0.6 29 and without a popcorn coupon is 0.371. if you buy 29 movie tickets we want to know the probability that more than 16 of the tickets have popcorn coupons. Considered tickets with popcorn coupons as successes in the Binomial Distribution? do not include p= in your answer
- Question: identify the parameter n in the following binomial distributions senerio a … coin has a 0.41 probability of landing on heads and 0.55 9 probability of landing on tail. if you toss the coin 19 times we want to know the probability of getting heads more than 5 times (consider a toss of heads as success in the Binomial Distribution)
- Question: a basketball player has a 0.689 probability of making a free throw if the player shoots 18 free throws what is the probability that he makes no more than 11 of them. round your answer to three decimal places
MATH 225N Week 4 Assignment: Evaluating Probability with the Binomial Distribution
- Question: Boris is taking a quiz for an online class. For the quiz, the system randomly assigns 2 high-difficulty questions, 7moderate-difficulty questions, and 6 low-difficulty questions. What is the probability that Boris is … a moderate-difficulty question first? Give your answer as a fraction.
- Question: A baker finds several new recipes to try. Of the new recipes, there are 11for cookies, 10 for muffins, and 4 for cakes. If the baker selects a recipe at random, what is the probability the recipe is for a cake? Give your answer as a fraction.
- Question: The table below shows a probability density function for the discrete random variable X, the number of times students had to retake a math test until they … a perfect score. What is the probability that X is 0 or 2? Provide the final answer as a fraction.
- Question: The table below shows a probability density function for a discrete random variable X. What is the probability that X is 0, 3, or 5? Provide the final answer as a fraction.
- Question: Which of the following tables shows a valid probability density function? Select all correct answers. Select all that apply:
Example
- You are flipping three fair coins, and want to know the possible outcomes.
- Let the random variable X = the number of heads you get when you toss three fair coins.
- The sample space (possible outcomes) for the toss of three fair coins is TTT, THH, HTH, HHT, HTT, THT, TTH, HHH. (H = heads; T = tails)
- So, x = 0,1,2,3, because when you toss three coins, you have the possibility of getting 0 heads, 1 head, 2 heads, or 3 heads.
