Sagot :

350 - 250 + 120 = 220 draw a ven diagram it will help

Answer:

A. 220

Step-by-step explanation:

Please see the attached for the venn diagram

Given that the total number of male athletes is 350

Let

Total number of male athletes = N

n(Bk) = number that play basketball

n(Bb) = number that play baseball

n(k) = number that play basketball only

n(x) = number that play baseball only

n(b) = number that play both

Then it is given that

n(Bk) = 250 , n(b) = 120

n(Bk) = n(b) + n(k)

250 = 120 + n(k)

n(k) = 250 - 120

      = 130

N = n(k) + n(x) + n(b)

350 =  130 + 120 +  n(b)

350 = 250 + n(b)

n(b)  = 350 -  250

n(b)  = 100

n(Bb) =  n(b) + n(x)

n(Bb) = 100 + 120

         = 220
