The definition of sine is "opposite / hypotenuse".
So, it is safe to assume that hypotenuse = 38.
Answer:
6%
Step-by-step explanation:
The probability of picking a maths student = 21% = 21/100
The probability of picking a science student = 15% = 15/100 = 3/20
The probability of picking in both = 6/100 = 3/50
The probability that the student is in maths or science = 21/100 - 15/100 = 6/100 = 6%.
