Step-by-step explanation:
let the number of questions solved by Andy=x
this implies that 6+x=10
making x the subject of the equation
x=10-6
x=4
therefore Andy solved 4 questions
• 108 total plastic chips
• #chip > 44 = 108 - 44 = 64 chips
• 64 chips / 108 chips total
• That simplifies to: 16/27 probability
