Respuesta :

Answer:

Probability of  both English and Maths =  17%

Step-by-step explanation:

Probability of English or Maths

100 -70 = 30%

Probability of English or Maths =

Probability of English + Probability of Maths + Probability of  both English and Maths

30 % = 22% + 25 % + Probability of  both English and Maths

Probability of  both English and Maths = 47% - 30 %

Probability of  both English and Maths =  17%
