Cards with the numbers 1 through 50 are placed in a box and thoroughly shuffled.

I wish i could help you but i really didnt pay attention in class when i was learning probability sorry :(
You are picking a card out of 50.
Now you need to find out how many cards are the desirable outcome.
How many cards are less than 10?
Less than 10: 9 cards
Aren't all numbers 1 through 9 less than 10?
That means there are 9 cards with numbers less than 10.
Now we need to see how many cards are multiples of 12.
Which numbers from 1 to 50 are multiples of 12?
um 2 6 3 4
24, 36, and 48 am i right @mathstudent55
Also, 12 itself.
12 is a multiple of itself, so the multiples of 12 from 1 to 50 are
12, 24, 36, and 48
That makes sense.
Now you see you have a total of 9 + 4 = 13 cards that are you desired outcome.
The probability of an event happening is the number of desired outcomes divided by the total number of possible outcomes. You have 13 desired outcomes, and a total of 50 outcomes. What is the probability?
13/50 ? C
Right, because you can't simplify it anymore.
p(choosing a number less than 50 or choosing a multiple of 12) = 13/50
