Part A
Use the binomial probability distribution formula.
p = 0.54 = probability of getting a purple marble
n = 5 = sample size
x = 2 = number of purple we want to get
The portion is from the nCr combination formula. The exclamation marks indicate a factorial.
Alternatively, you could use Pascal's Triangle for that portion.
<h3>Answer: 0.283831776</h3>This decimal value is exact. Round it however you need to.
============================================================
Part B
To find the expected value, aka the mean, we multiply the sample size and probability of getting a purple marble on any single selection.
n*p = 5*0.54 = 2.7
<h3>Answer: 2.7</h3>Answer:
The correct choice is C
Step-by-step explanation:
The given function is:
The degree of this function is odd so the function will rise at one end and fall on the other end.
Since the coefficient of the leading term is negative, the graph of the function will rise at the left and fall on the right.
The correct answer is option C.
