- BBC GCSE Question
Not sure if I am losing it but this seems like nonsense.
MATHS: A pet shop had 40 rabbits.
22 were male.
The others were female.
The shop sold 10 of the rabbits.
The probability that a rabbit picked at random is male is now 1/2 (0.5).
How many female rabbits were sold?
Choices 3, 4 or 5.
It’s 3. There were 18 rabbits (40-22=18) originally. To have a 1/2 (one-in-two) chance of picking out a male after 10 were sold, there would need to be 15 of each sex – so 18-15=3.Posted 2 years ago
