Question

Only the answer for both

In the experiment of rolling two fair 6-sided dice, Leonard considers the outcome a "success" if the sum of the die results is either 5 or 6. Leonard performs this trial 4 times. In tossing two fair coins, Mildred considers the outcome a "success" if both coins land on "Heads." Mildred performs this trial 3 times. In rolling a fair 4-sided die (with edges numbered 1, 2, 3, and 4, respectively), Nigel considers it a "success" if he rolls a "1." Nigel performs this trial 5 times. Among the (collective) trials of Leonard, Mildred, and Nigel, what is the probability that exactly 3 successes occur? (Answer as a decimal number, and round to 3 decimal places).

5 and a = 0.56, that X2 is a Suppose that X1 is a negative binomial random variable with parameters k negative binomial random variable with parameters k2 = 8 and a2 = 0.5, and that X3 is a negative binomial random variable with parameters k3 4 and az = 0.69. If X1, X2, X3 are independent, then find the standard deviation of 3X1 – «X2 + V2X3. (Answer as a decimal number, and round to 3 decimal places).
