For those who are 5 to 10 years of age, 19% have inadequate calcium intake. For those who are 11 to 13 years of age, 56% have inadequate calcium intake. Let A denote "5 to 10 years old and Ac denote 11 to 13 years old". (these are the only two age groups under consideration). Let C denote "adequate calcium intake and C denote "inadequate calcium intake Obtain P(CC). (Round your answer to four decimal places)

Answer 1

Please give me ?

Solutions- A: 5-10 years old, PCO) - 54/100 AC:11-13 years old pla°): 46100. then Ci adequate Calcium. de note inadequate Calcium, so PLETA) = 16 l P (EAC) = 50 00 PCC")= ? P(ance) – 4 x PCA) = 4 * * P(ance) = CO * PCA) - X 480 P(*) = (Anc)+ P(nacº) tooo [12x54 +56 x 46] = 0.3602 P(c) = 0.3602
