Answer:
Answer explained below
Step-by-step explanation:
Alex has in the past committed 55% of the burglaries committed by the three, Becky 31%, and Carl the rest, hence
probability, P(Carl doing a burglary) = 1 - P(Alex or Becky doing a burglary)
= 1 - (0.55 + 0.31)
= 0.14
a) P(next burglary in town is the burglary of a residence) = P(Alex did a burglary of a residence) + P(Becky did a burglary of a residence) + P(Carl did a burglary of residence
= 0.55*1/3 + 0.31*0.5 + 0.14*1
= 0.4783
b)From Bayes' Theorem: P(A | B) = P(A & B) / P(B)
Hence,
P(Becky | a resident reports a home burglary) = P(Becky did a burglary of a residence) / P(burglary of a residence)
= (0.31 * 0.5)/0.4783
= 0.3240
Answer:
you find the sum by adding a "0" at the end of "4.2" and the stack add them (or however you can add them).
Step-by-step explanation:
4.20
+ 2.14
= 6.34
Answer:
7.38461538462
Step-by-step explanation:
1/2x6/5=3.25
24/3.25=7.38461538462
12 - 5(3r + 2) = 17 |use distributive property a(b + c) = ab + ac
12 - 15r - 10 = 17
2 - 15r = 17 |subtract 2 from both sides
-15r = 15 |divide both sides by (-15)
r = -1
