Using the binomial distribution, the probabilities are given as follows:
a. 0.2637 = 26.37%.
b. 0.8965 = 89.65%.
c. 0.0148 = 1.48%.
<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.
The values of the parameters for this problem are:
n = 5, p = 0.25.
Item a:
The probability is P(X = 2), hence:
Item b:
The probability is:
In which:
Then:
Item c:
The probability is:
In which:
Then:

The converse of a mathematical statement involves simply switching the hypothesis and the conclusion, thus:
"If a triangle is isosceles, then it is equilateral."
Answer:24+4x
Step-by-step explanation:
a=5. PHOTO
b=7. PHOTO
a1=5+x. FRAME
b1=7+x. FRAME
Pf=2*(a1+b1)
Pf=2*(5+x+7+x)
Pf=2*(12+2x)
---------Pf=24+4x. - - - - - - PERIMETER OF FRAME
