Using the binomial distribution, the probabilities are given as follows:
a) 0.4159 = 41.59%.
b) 0.5610 = 56.10%.
c) 0.8549 = 85.49%.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
For this problem, the values of the parameters are:
n = 3, p = 0.76.
Item a:
The probability is P(X = 2), hence:


Item b:
The probability is P(X < 3), hence:
P(X < 3) = 1 - P(X = 3)
In which:


Then:
P(X < 3) = 1 - P(X = 3) = 1 - 0.4390 = 0.5610 = 56.10%.
Item c:
The probability is:

4 because 4 x 4 =16 and 4+4=8
The total is $15.04 because you must add 12.74 + 2.30
Answer:
1.31
Step-by-step explanation:
=
^2 x
^3 x 2.48
= 1.31 x 0.40 x 2.48
= 0.524 x 2.48
= 1.31
:)
Answer was verified and rounded
if a is related to b by some property, and b is related to c by the same property, then a is related to c by that property (Brainliest Answer Will be appreciated:D)
