Answer:
Step-by-step explanation:
The number of adults that use smartphones in meetings or classes follows a binomial distribution. So, the probability that x adults use their smartphones in meetings or classes is calculated as:
Where, n is the number of identical and independents events, in this case, 7 adults with smartphones. p is the probability of success or the probability that the adult use the smartphone in meeting or classes, in this case, p is equal to 0.58
So, replacing values, we get that the probability that x adults use their smartphones in meetings or classes is:
Now, the probability that at least 2 of them use their smartphones in meetings or classes is calculated as:
Where:
Finally, is equal to:

I’m pretty sure it’s the way you have it. 360t+1013-12012
if not...someone else will probably tell you the right way
Plotting is the place the dots belong to?
If you want to do a positive of which is like (x,5) then you go to in between the right top and bottom or x axis where the positives are and count, if the (2,y) is positive you count and go up if y is a negative then you count down how many number there is.
Let’s use (1,-1) first you go into the x-axis, one is a positive so you go to one in there, and go down one or to -1 bc the -1 is a negative and the digit is 1. ( I hope it made sense, if u need more help u can tell me.)
