(3/4, -1/8)
The slashes represent fractions "/"
Answer:
180
Step-by-step explanation:
add 1% to 31.50 to get 31.815
then take the total 5276.70 and divide by 31.815
Probability hit target P(A) = 0.3
Probability hit target P(B) = 0.4
Probability hit target P(C) = 0.5
Probability not hit target P(A) = 0.7
Probability not hit target P(B) = 0.6
Probability not hit target P(C) = 0.5
(i) That all the missiles hit the target?
= P(A) . P(B) . P(C)
= 0.3*0.4*0.5
= 0.06
(ii) That at least one of the four hits the target?
At least one hit the target = 1 – P(no hit the target)
= 1 - P(A) . P(B) . P(C)
= 1 – 0.7*0.6*0.5
iii) That exactly one hits the target?
exactly one hits the target = P(A).P(B).P(C)+ P(A).P(B).P(C) + P(A).P(B).P(C)
vi) That exactly 2 hit the target?
= P(A).P(B).P(C)+ P(A).P(B).P(C) + P(A).P(B).P(C)
I'm not understanding the question exactly but i will try my best ::
I think that you want it as a fraction : 1/2
you will split it in to two equal parts from one whole
