Suppose that a box contains 7 cameras and that 3 of them are defective. A sample of 2 cameras is selected at random, with replacement. Define the random variable X as the number of defective cameras in the sample.

Suppose that a box contains 8 cameras and that 4 of them are defective. A sample of 2 cameras is selected at random. Define the random variable Xas the number of defective cameras in the sample. Write the probability distribution for X.Write your answer in fraction form or round to 3 decimal places.

Suppose you model a game of chance with a discrete probability distribution. Let X be the net amount of money or lost by the player. Let pX be the probability of the corresponding outcome. The three events are as follows: There is a 23% chance the player wins 7 dollars. there is a 38% chance the player loses 4 dollars. there is a 39% chance the player breaks even.

Based on a​ survey, assume that 27​% of consumers are comfortable having drones deliver their purchases. Suppose that we want to find the probability that when five consumers are randomly​ selected, exactly two of them are comfortable with delivery by drones. Identify the values of​ n, x,​ p, and q.
