Identify the parameter nin the following binomial distribution scenario. A basketball player has a 429 probability of making a free throw and a 0.571 probability of missing. If the player shoots 20 free throws, we want to know the probability that he makes no more than 12 of them. (Consider made free throws as successes in the binomial distribution.) Give the numerical value of the parameter pin the following binomial distribution scenario…..A softball pitcher has a 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. Identify the parameters pand n in the following binomial distribution scenario……Jack, a bowler, has a 38 probability of throwing a strike and a 0.62 probability of not throwing a strike. Jack bowls 20times (Consider that throwing a strike is a success.)…….The Stomping Elephants volleyball team plays 30 matches in a week-long tournament. On average, they win 4 out of every 6matches. What is the mean for the … number of matches that they win in the tournament? Using the same scenario, what is the standard deviation for the number of matches that they win in the tournament? The Stomping Elephants volleyball team plays 30matches in a week-long tournament. On average, they win 4 out of every 6 Identify the parameter nin the following binomial distribution scenario. A weighted coin has a 441 probability of landing on heads and a … 0.559 probability of landing on tails. 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.) Give the numerical value of the parameter n, the number of trials, in the following binomial distribution scenario. A weighted coin has a 486probability of landing on heads and a 0.514 probability of landing on tails. If you toss the coin 27 times, we want to know the probability of getting heads exactly 11 times. Consider a toss of heads as success in the binomial distribution. The probability of winning on an arcade game is 659. If you play the arcade game 30times, what is the probability of winning exactly 21 times? The probability of buying a movie ticket with a popcorn coupon is 526. If you buy 26movie tickets, what is the probability that exactly 15 of the tickets have popcorn coupons? The probability of buying a movie … ticket with a popcorn coupon is 608. If you buy 10movie tickets, what is the probability that more than 3 of the tickets have popcorn coupons? (Round your answer to 3 decimal places if necessary.)

(Round your answer to 3 decimal places if necessary.) A 2014 study by researchers at the University College Antwerp and the University of Leuven showed that e-cigarettes are effective at reducing cigarette craving. Participants were separated into two groups. One group was … e-cigarettes and the other was told to not smoke e-cigarettes. Two months later, researchers observed how many participants had … stopped smoking cigarettes……..The following table shows approximate numbers. According to the table, what is the probability that a randomly … participant did not stop smoking, … that the participant received an e-cigarette?
