FISHY PROBABILITY AIM: Understand how to express probability as a fraction
What is the probability of catching a goldfish? J P(Goldfish)=1414
What is the probability of catching a blue fish? J P(Blue fish)=3434
What is the probability of catching a goldfish? J P(Goldfish)= 3636 = 1212 If another goldfish swims into the tank what is the probability of catching a goldfish now? P(Goldfish)= 4747
What is the probability of catching a blue fish? J P(Blue fish)= 5858 If another blue fish swims into the tank what is the probability of catching a blue fish now? P(Blue fish)= 6969 = 2323
How many goldfish need to swim into the tank to make the probability 2 ? 5 J
How many goldfish need to swim into the tank to make the probability 1 ? 2 J
How many blue fish need to swim into the tank to make the probability 2 ? 3 J
