Answer:
The required probability is, 0.78
Step-by-step explanation:
There are, (52 - 13) = 39 cards which are not spade
5 cards can be chosen from the deck of 52 cards in
ways
and out of these 5 choices, none of them will be spade in,
ways
So,
P(None of the chosen cards is spade)
= 

Hence,
P(out of these 5 choices, at least one card is spade)

= 0.78

This is what I got and hopefully it helps.
1.A The dot is not filled and it points in the left direction
2.B The dot is filled and it points to the left
3.A The dot is not filled and it is pointed in the left direction
4.C The dot is filled and is pointing in the right direction.
Whenever you have a filled dot it will always be a greater than or equal to or less than or equal to. When the dot is not filled, the answer will always be greater than or less than.
a(n) = 6n - 7
a(12) = 6(12) - 7
a(12) = 72 - 7
a(12) = 65
The answer is B.
