A card is drawn from a
standard deck of cards,
then a month of the year
is chosen What is the
probability of getting a
diamond or a 7, then
November?

1 / 39

Step-by-step explanation:

There are 13 diamond, 4 7s' in 52 cards  ( one of 7 included in 13 diamonds)

getting a diamond or a 7: (13 + 4 - 1) /52 = 16 / 52 = 4 / 13

pick November: 1 / 12

4 / 13 * 1 / 12 = 4 / 156 = 1 / 39

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
