Uhhhhhhhh I need points SORRY
Answer:
x=1/2 or 0.5
B. 0.5
Step-by-step explanation:
Step one: Add x to both sides
you then get the equation 7=4x+5
Step two: subtract 5 from both sides
you then get the equation 2=4x
Divide both sides by 4 to undo the multiplication.
2/4=4x/4x
you get x=2/4 which simplifies to 1/2.
Answer:
P(X<3) = 0.01004
Step-by-step explanation:
From the given information:
Consider the application of Poisson distribution
with the parameter
;
Therefore, we can calculate the required probability as follows:
P(X< 3) = P(X = 0) + P(X = 1) + P(X =2)


P(X<3) = 0.01004
