Question

A single card is drawn from a deck. Find the probability of selecting a 10 or a diamond.?

Answer 1

Picking a diamond would be a 1 in 4 chance

Picking a 10 would be a 4 in 52 chance

Answer 2

I am SADDEND by the pathetic mathmitical answers to the simplistic question,,,,,,,,,, ugh,,,

PICKING A DIAMOND1 in 4 (a 25% chance)

PICKING A 10 would be 1 in 13 (a 8% chance)

good luck,,, you will probably get answers like mine (the good answers) in the math sections,,,

Answer 3

there are 13 diamonds, one of which is a ten of diamonds, then ontop of that there are three more tens for a total of 16 cards, 16 cards out of a total of 52 that are aimed for selection makign the odds 16:52  

(4:13)

Answer 4

there are 4 10's and 12 remaining diamonds.  That gives you 16 chances in 52 or 4 in 13.  That's a 32.5% chance.

Answer 5

There are 52 cards in a deck.  The probability of selecting the ten of diamonds is 1/52.  There are 12 other diamonds remaining, so the probability of selecting any other diamond is 12/52.  There are 3 other 10s remaining, so the probability of selecting an other 10 is 10/52.

Thus, the probability of selecting a 10 or a diamond is 1/52+12/52+10/52 = 23/52.

You could also look at this as the probability of selecting a 10 plus the probability of selecting a diamond minus the probability of selecting something that is both a 10 and a diamond, which gives 13/52+4/52-1/52=23/52.  This is known as the inclusion-exclusion principle.
