Answer 1

Answer:

Sara has 20 sweets.she has 12 liquorice,5 mint sweetened 3 humbugs.sara is going to take at random 2 wettest. work out the probability

Answer 2

Answer:111/190

Step-by-step explanation:

1.)Work out the probability of getting 2 of each sweet:

Probability of 2  Liquorice,=(12/20)×(11/19) =132/380

Probability of 2  mints=(5/20)×(4/19) =20/380

Probability of 2  Humbugs=(3/20)×(2/19) =6/380

Probability that the 2 sweets will be the same=132/380+20/380+6/380=158/380

2.)Take away the total that you got from 1 (1-158/380).

Probability that the 2 sweets will not be the same=1−158/380=222/380=111/190

Hope this helps! :))
