In a class of 29 students, 20 play an instrument and 18 play a sport. There are 11 students who play an instrument and also play a sport. What is the probability that a student chosen randomly from the class plays a sport and an instrument?

answer: 40392

step-by-step explanation:

10098 x 4 = 40392

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
