A: For m = 5: P(³≥1) = 1 – P(³=0) = 1 – 0.9973^5 = 0.0134
M = 10: 1 – 0.9973^10 = 0.0267
M = 20: 1 – 0.9973^20 = 0.0526
M = 30: 1 – 0.9973^30 = 0.0779
M = 50: 1 – 0.9973^50 = 0.126

Going by the question and the explanation above, we derived sample values of the mean as well as standard deviation in calculating our probability, since that is the necessary value in determining the probability of an out-of-bounds point being plotted. Furthermore, we would know that that value for the possibility would likely be a poor es²ma²on, cas²ng doubt on anycalcula²ons we made using those values
 
        
             
        
        
        
Answer:
Avg speed 550 miles per hour
Step-by-step explanation:
with the wind 1200 miles traveling 
1200/(550+50) = 2 hours
Against the wind 
1000/(550-50) = 2 hours
 
        
             
        
        
        
Let, the number of toy trucks = x
Then, number of toy cars = (x + 12)
Now, we have: x + x+12 = 38
2x + 12 = 38
2x = 38 - 12
2x = 26
x = 26/2
x = 13
So, there are 13 toy trucks in total.
Hope this helps!
