Sоme species оf Wildflоwer seeds hаve а 75% chаnce of growing into a seedling. From a very large packet containing thousands of Wildflower seeds, you randomly select seven seeds and plant them. Let X = the number of seeds that grow into a seedling. The distribution of X is binomial. a. What is the number of ways that four seeds from seven could grow into a seedling? [ways] b. What is the probability that exactly five seeds grow into a seedling? [binprob] c. What is the probability that at least one seed grows into a seedling? Note: ^ means "to the power of". For example, 3^7 means . [atleastone] d. You decide to keep planting seeds until fifteen seeds grow. Is this a binomial distribution? [cond]
