Answer :
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
