I don't know how to explain sorry
First we need slope


Put D co-ordinates on y=mx+b




Now
slope intercept form.

Answer:
The probability of 1 error in a period of 0ne - half minute is 0.1494
Step-by-step explanation:
Formula for poisson distribution:

If there is an average of 1 error in 10 seconds
In one-half minutes (i.e. 30 seconds), there will be an average of 30/10 errors = 3 errors


1! = 1

P(X = 1) = 3 * 0.0498
P(X = 1) = 0.01494
0.3, 0.03,0.003
Because 0.3 is equivalent to 3/10
Because 0.03 is equivalent to 3/100
Because 0.003 is equivalent to 3/1000
