Only 27.5% of all widgets are green. If four widgets are randomly selected, what is the probability that at least one of them is green?

0.0057

Step-by-step explanation:

Let X be a binomial variable that represents the number of widgets are green.

Given : Probability that a widget is green = 0.275

Sample size : n= 4

Binomial probability distribution formula:

Now, the probability that at least one of them is green will be

Hence, the probability that at least one of them is green = 0.0057

6 (3) - 4 + 32

hope this

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
