Answer:

13ab

Step-by-step explanation:

When you add the 5 and 9 it will give you 14 but you still have to subtract the 1ab(there is a 1 in front of variables that don't have a visible number.) So it will be 13 a b.

Shannon rolls a number cube and then chooses a card from set of cards numbered 1 through 5. What is the proability that she will
Anuta_ua [19.1K]
Half of the numbers on the cube are even, so there's a 1/2 chance that that number is even.  3/5 of the numbers on the cards, however, are odd.  The chance that both of these occur is 3/5*1/2=3/10.
