Determine, if possible, if (x – 8) is a factor of (x3 – 3x2 – 31x – 72)
the formula to find the probability is p(a ∩ b)=p(b | a)p(a) and p(a ∩ b) = .
total numbers in the hat = 30
let a be the event of picking number 1 and b be the event of picking number 2 then without replacement.
clearly, the probability of the second event depends on the first event.
so, p(a ∩ b)=p(b | a)p(a)
p(b | a) means probability of event b with the condition that event a has happened.
so, the first number picked is 1.
therefore, p(b | a) =
p(a ∩ b)=
the answer would be 91 customers
the measure of ∠1 is 63°
vertical angles are non-adjacent angles that form on either side of intersecting lines. as a result, the two angles are congruent.
