Question

Two pennies, a nickel, and a dime are placed in a cup. You draw a first coin and then a second coin.

Answer 1

Answer:

a) {P1P2, P1N, P1D,P2P1, P2N,P2D,NP1,NP2,ND,DP1,DP2,DN}  

PP=2/12 NP=4/12 DP=4/12 DN=2/12                                                                                                        

b) 1/3

Step-by-step explanation:

Let us call pennies by P1 and P2.

a)There are 12 possible outcomes as it is written above.

b)In order to have 11 cents we need a penny and the dime. There are 4 such possibilities (events). The total number is 12. So the probability is 4/12.
