Workers are grouped by their areas of expertise and are placed on at least one team. 20 are on the marketing team, 30 are on the

liubo4ka [24]

Answer: C. 74

Step-by-step explanation:

Let M= Number of workers are in marketing team .

S = Number of workers are in Sales team.

V = Number of workers are in Vision team.

As per given , we have

n(M) = 20 , n(S) = 30 , n(V) = 40

n(M∩S) = 5 , n(V∩S) = 6 , n(M∩V) = 9

n(M∩S∩V) =4

Using formula of sets , we get

n(M∪S∪V) =n(M)+n(S) +n(V) -n(M∩S) - n(V∩S)-n(M∩V) +n(M∩S∩V)

Substitute the corresponding values , we get

n(M∪S∪V) =20+30+40-5-6-9 +4

= 74

∴ The number of workers are in at least one team = 74

Therefore , the total number of workers =74

Hence, the correct option is : C. 74
