- Part a) A probability function assigns numbers between 0 and 1 to events according to three defining axioms. State the definition of a probability function.Assume that when adults with smartphones are randomly selected, 38% use them in meetings or classes. If 25 adult smartphone users are randomly selected, find the probability that exactly 16 of them use their smartphones in meetings or classes. The probability is (Round to four decimal places as needed.) ry nsWhen a bit is transmitted, it is received in error with probability p. Assume that 10 bits are transmitted independently, what is the probability that 4 bits are correctly received?
- if the events have the same theoretical probability of happening, then they are called Mutually exclusive events Mutually exhaustive events Equally likely events Impossible events BackMAN Assume that when human resource managers are randomly selected, 62% say job applicants should follow up within two weeks. If 7 human resource managers are randomly selected, find the probability that exactly 4 of them say job applicants should follow up within two weeks. The probability is (Round to four decimal places as needed.)Please no written by hand
