Question

The probability of getting a rotten
apple in a box of 400 apples is 0.035.
Find the number of good apples. [3]​

Answer 1

Answer:

p(rotten) 0.035

number of rotten apples 0.035*400=14

number of good Apples =400-14=386

Answer 2

$Number \:apples \:in \:a \:Box = 400$

$Let \: number \: rotten \: Apples = x$

$P\pink { (Rotten )} = 0.035 \: (given)$

$\implies \frac{x}{400} = 0.035$

$\implies x = 0.035 \times 400$

$\implies x = 14$

$Number \:of \:Good \: Apples = 400 - x \\= 400 - 14 \\= 386$

Therefore.,

$\red {Number\:of \:Good \: Apples}\green {=386}$
