Use the binomial formula to calculate the following probabilities for an experiment in which n = 5 and p = 0.4; a. the probability that x is at most 1.
b. the probability that x is at least 4.
c. the probability that x is less than 1.

s

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

well kind of. you get friend requests. and you can accept them or not so yes.
