1. 7.2 Binomial Distribution

2. Binomial Distribution Today we are going to introduce the Binomial Distribution. This type of distribution is used in situations where: There is only 2 possible outcomes (Success or fail, True or false, Yes or No). The events are independent. The Random Variable is the number of successes.
3. Binomial Distribution A Tennis Racquet manufacturer strings rackets to 55 Lbs. tension on the strings and says the racquets could have an error of plus/minus 2 lbs. From quality control testing, the manufacturer knows that about one in six racquets is actually within plus/minus 0.5 lbs of 55. Roger Federer needs his racket to be within 55lbs. What is the probability that Roger could find exactly 3 racquets among the first 5 tested?
4. Binomial Distribution Long Way using Probabilities and Multiplying Short way using Binomial Distribution Formulas
5. Binomial Where p is probability of success on an individual trial, and q= 1-p is the probability of failure
6. Is it Binomial? There is only 2 possible outcomes (Success or fail, True or false, Yes or No). The events are independent. The probabilities for each trail are independent. The Random Variable is the number of successes.
7. Telephone Numbers Tan’s family moves to an area with a different telephone exchange, so they have to get a new telephone number. Telephone numbers in the new exchange start with 446, and all combinations for the fout remaining digits are equally likely. Tan’s favorite numbers are the prime numbers 2,3,5,7. Calculate the probability distribution for the number of these prime digits in Tan’s new telephone number.
