5x + 4y = 20
4y = 20 - 5x
y = 20/4 - 5/4x
y = 5 - 5/4x
The x intercept is when y = 0
0 = 5 - 5/4x
5/4x = 5
x = 4.5/5
x = 4
The y intercept is when x = 0
y = 5 - 5/4x
y = 5 - 5/4.0
y = 5
The required probability of success is given by 0.98906500
Assume the random variable X has a binomial distribution with the given probability of obtaining a success.
P(X<5), n=6, p=0.3
<h3>What is binomial distribution?</h3>
In binomial distribution for number trials we are investigating the probability of getting a success remain the same.
n = number of trails,
p = probability of success
x = the number of success
p(x<5) = P(x=0)+ p(x=1) + p(x=2)+p(x=3)+p(x=4)
= 
p(x<5) = 0.98906500
Thus the required probability of success is given by 0.98906500

Im pretty sure it’s:
p’ = 12(5)=60
a’ = 9(5^2)=225
you probably don’t have to include the equation, but i wanted to put it in there just in case :-)
