Consider the following table that categorizes the injuries that occured in one season in a particular hockey league. The table shows which injuries happened to someone wearing a half face shield versus a full face shield.
(H) (F) (T)
Head or face injury only (A) 95 34 129Totals 347 229 576
Neck injury only (B) 41 38 79
Body injury only (C) 9 7 16
Multiple injuries 202 150 352
(c) Determine whether the events F and B (as shown in the table) are independent.
(a) Calculate the probability that a randomly selected injured person from those represented in the table had only a neck injury.
(b) What is the probability that an injury that occurred to someone wearing a full shield resulted in only a neck injury?
would a) be the total injuries choose neck injuries?
is my thinking right here? then B would be fullshield neck injury from the total??
