32 Cards are left to be signed.
What is probability ?
- The proportion of all conceivable outcomes to the number of outcomes in an exhaustive set of equally likely outcomes that result in a certain event.
- Example -Since there is a 50% chance that the outcome will be heads, we can anticipate 50 heads.
total cards are 75,
then , 2/5 of 75 = 30.
now left cards 75 -30 = 45
That leaves 45 cards
1/9 of 45 = 5 cards,
so 45 -5 = 40 ⇒ that leaves 40.
now,
Calculate 20% of 40,
40 × [tex]\frac{20}{100}[/tex] = 8
that is 8 cards.
cards are left to be signed 40 - 8 = 32
Therefore, 32 Cards are left to be signed.
