Probability, please help.
hi, i've been stuck on this question for a while now and i was wondering if anyone would be able to lend a hand and help me work it out. It would be much appriciated!
Q-22 students were asked if they had a previous broken leg (group L), broken arm (group A) and jaw (group J).
One student has suffered niether.
17 students have suffered broken legs, 12 for broken arms, 8 for broken jaws.
There are 8 who have suffered a broken arm and leg, 6 for a broken arm and jaw and 6 for broken leg and jaw.
There were 9 who have broken exactly one of either a leg, arm or jaw.
Draw this as a Venn Diagram table and indicate clearly the number of student in each region
thank you xxx
