Step-by-step explanation:
the number of pupils are in the lower school
= (1- 1/5 - ¼) × 600
= (20/20 - 4/20 - 5/20)×600
= (11/20) ×600
= 330 pupils
No the answer to the solution would be 7
It is a 125% increase from 20 to 45

ON a die, the probability of getting a number less than 4:
P (

if this is wrong im very sorry, not on top on my math at the moment
