Catherine is doing the school pick up and has taken some cold treats for her children and their friends to enjoy. Catherine has a cool bag containing fabs, lemonade ice lollies and rockets.
She has 20 ice lollies altogether in her cool bag.
Catherine’s daughter chooses one ice lolly at random from the bag.
The probability that she chooses each type of ice lolly is:
Rocket = 0.1
Fab = 0.3
Lemonade ice lolly = 0.6
How many fabs does Catherine have in her cool bag?
Answer:
Since the probability of getting a fab is 0.3 and the total number of ice lollies is 20
0.3 x 20 = 6
