Answer 2

Answer:

(a) 0.33

(b) 0.67

Step-by-step explanation:

Total no. of outcomes = 100

P(E) = no. of favourable outcomes / no. of total outcomes

(a) P(chosen student likes science) = no. of students likes science / total no. of students

= 33/100

= 0.33

(b) P(chosen student likes maths) = no. of students likes maths/ total no. of students

= 67/100

= 0.67
