Abag is filled with 20 pieces of candy a and 10 pieces of candy b. if you choose 2 pieces of candy at random without replacement, what is the probability of picking one piece of candy a first and one piece of candy b second?

0.2298

Step-by-step explanation:

Number of pieces of candy A in the bag = 20

Number of pieces of candy B in bag =10

Total number of pieces =10+20=30

Probability of picking candy A first

Now total number of pieces in the bag =30-1=29 as one piece of candy A is picked out

Now the probability of picking of candy B

So the required probability

one that is bigger than 3 1/2
