A.T.Q, equation would be:
3x-18 = 2x
3x-2x = 18
x = 18
The number is 18
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.
3/4 - 5/9 .....common denominator is 36
27/36 - 20/36 =
7/36 <==
