Mean for each hour = 1
Mean for four hours, m = 4
P(x,m)=m^x*e^(-m)/x!
where x is number of defects.
P(X<=3,4)
=P(X=0,4)+P(X=1,4)+P(X=2,4)+P(X=3,4)
=0.01832+0.07326+0.14653+0.19537
=0.43355
Probability of at most 3 defects in four hours is 0.43355
Answer:
60
Step-by-step explanation:
60 ÷ 2 = 30
60 ÷ 3 = 20
Have a nice day :)
The constant variation of y=15x is 15 and the constant variation of y=8x is 8 :)
Answer:
122
Step-by-step explanation:
Plug in 1 for x and 11 for y
1 to the power of any number will always equal 1
I hope this helps!
