Answer #1

The probability that a person feels that he/she studied enough for a test = p = 0.64

X = Number of persons out of the 6 randomly selected people feel that he/she studied enough for the test

P(X=x) =

Since the selection is random, so the event that a selected person feel that he/she studied enough for the test is independent of the selection of other persons.

So, the probability distribution table is given by :-

X=x 0 1 2 3 4 5 6
P(X=x)
0.00218
0.02322
0.1032
0.24461
0.32615
0.23193
0.06872

Discrete Math: The Birthday Problem investigates the minimum number of people needed to have better than a 50% chance of at least two people have the same birthday. Calculating this probability shows that n = 23 yields a probability of approximately .506. Use the probabilistic algorithm called the Monte Carlo algorithm and find the number of people in a room that yields an approximate probability greater than .75. Please use the following list to complete the problem ● Adopt the...
