Probability: bernoulli trial model

Use the Bernoulli model to solve: A) Calculate probabilites of gettin from 0 to 5 clubs on a hand B) What is the probabilty of gettin 2 or fewer cubs of 5 cards?

Normal Distrubution

An airline wants to find out how long it takes for a travel agent to complete an airline ticket order from a computer terminal. Assume that the mean transaction time is 150 seonds. also assume that the population of transaction times has normal frequency curve. Find the probability that the 150 and 175 seconds to complete if standard deviation is 30 seconds.

Use a tree diagram to determine probability. Determine the probability that a child chosen at random from the school is bussed to school.

Draw a tree diagram that illustrates the following. Three-fifths of kindergarten children are bussed to school, while two-fifths of the first to fifth graders are bussed. The school has grades K through 5, and 17.5% of the students are in kindergarten. Determine the probability that a child chosen at random from the school is bussed to school.

Determine probability

A man has been guessing colors of cards drawn from a standard deck of cards. During the first 50 draws he kept track of the number of cards of each color. What is the probability of guessing the color of the fifty-first card?

Determine Probability distribution

In a certain carnival game a player pays $1 and then tosses a fair coin until either a "head" occurs or he has tossed the coinfour times. He receives fifty cents for each toss. Determine the probability distribution for the experiment of playing the game and observing the player's earnings.
