In a school one-third of all 240 students play soccer. Forty four students play both soccer and basketball and sixty students do
stiv31 [10]

Answer:

100 students play only basketball.            

Step-by-step explanation:

We are given the following information in the question:

Total number of students in school = 240

Number of students that play soccer =

\dfrac{1}{3}\times \text{Total number of students}\\\\=\dfrac{1}{3}\times 240 = 80

n(S) =80

n(S\cap B) = 44

n(S'\cap B') = 60

Formula:

n(S\cup B) = \text{Total} - n(S' \cap B')\\n(S\cup B) = n(S) + n(B) - n(S\cap B)

Putting the values, we get,

n(S\cup B) =240-60=180\\n(S\cup B) = 180 = 80 - 44 + n(B)\\n(B) = 180 - 80 + 44= 144

Thus, 144 students play  basketball.

Out of these 144, 44 plays soccer as well.

\text{Student only playing basketball} = 144 -44 = 100

Thus, 100 students play only basketball and not soccer.
