Question

You are dealt one card from a 52-card deck. Find the probability that you are not dealt a spade.
A
4/13

B
1/4

C
2/5

D
3/4

Answer 1

numbered card, that is 2 through 10 or 9 per suite or 36 total, so the probability is 36/52 = 9/13 (if you count the ace as a numbered card, that changes it)
club, 1/4

If that means OR, or the sum of the two, that is more complicated because of overlap.
clubs are still 1/4, and number card for the other 3 suites is 9/39 = 3/13
so overall it is 1/4+3/13
or (13+12)/52 = 25/52

Answer 2

so C
