Question

5. Emily has a bag of 20 Fruit sweets

7 of the sweets are strawberry flavour

11 are lime flavour

2 are lemon flavour

Emily takes at random a sweet from the bag

Write down the probability that Emily:

Takes a strawberry flavoured sweet
Does not take a lime flavoured sweet
Takes an orange flavoured sweet

Answer 1

Explanation:

the total is 20.

7 of these 20 are strawberry flavor.

11 of these 20 are lime flavor.

2 of these 20 are lemon flavor.

remember, the probability is

desired cases / total possible cases.

so, the probability to pick a strawberry flavoured sweet is

7/20 = 0.35

to pick a not-lime flavoured sweet :

7 strawberry ones + 2 lemon ones = 9 desired cases. the probabilty is

9/20

the probability to take an orange flavoured sweet is 0.

because there are no orange ones in the bag.

therefore there is a 0 chance to pick one.
