The answer is B sorry i was wrong
Answer:
the required probability is 0.09
Option a) 0.09 is the correct Answer.
Step-by-step explanation:
Given that;
mean μ = 7
x = 4
the probability of exactly 4 bridge construction projects taking place at one time in this state = ?
Using the Poisson probability formula;
P( X=x ) = ( e^-μ × u^x) / x!
we substitute
P(X = 4) = (e⁻⁷ × 7⁴) / 4!
= 2.1894 / 24
= 0.0875 ≈ 0.09
Therefore the required probability is 0.09
Option a) 0.09 is the correct Answer.

20 get a ball because 60 divided by 3 equal 20 ab 15 get a ball because 60 divided by 4 equals 15
General form is ax^2 + bx + c = 0
so comparing the equation in the question to this we get:-
a = 1, b = -3 and c = -2 Answer
