Answer 1

Ok so we have
3 peices of gum
4 jaw breakers
13 sour punch straws
A total of 20 items in the bag

So we want to know what the probability that betsy will choose first a sour punch straw and then a jaw breaker

So the probability that Besty will choose a sour punch is 13/20

The probability that Betsy will choose a jaw breaker second is 4/19
Since one candy was already chosen so there are only 19 items in the bag now

So the probability that Betsy will chose the sour punch first and the jaw breaker second is
13/20*4/19=.1368

.1368*100=13.68 % which can be rounded to 13.7%
