Identify the type of distribution described as binomial, chi-squared, discrete probability or a normal distribution AND briefly explain why you chose this distribution type.

a.)

 Number of platforms = x 0 1 2 3 4 5 6 P(X) 0.03 0.06 0.19 0.14 0.36 0.17 0.06

b.) A completely fictitious poll of Easter basket recipients found that 78% of respondents disapproves of licorice (black) jelly beans. There were 576 people in the sample.

(A) It is discrete probability because the total sum of probability is equal to 1 and none of the probabilities is negative. We are provided with probabilities for each individual x value. So, it is discrete probability

(B) it is a binomial distribution because the probability of success is given as p = 0.78 with fixed number of trials n = 576

it is binomial because each trail is independent and number of trials is fixed

probability of failure is 1-p =1 -0.78 = 0.22
