What is the probability of rolling a 6 or a number less than 3?

evanhelps · Answer

So question is asking probability of rolling either 6, 2, or 1. So those are 3 numbers out of the possible 6, meaning you have a 1/2 or 50% chance.

Well you are given 3 numbers (6,2,1) 

You can put that over the total numbers

so 3/6, which can be reduced to what?

A box contains twenty cards numbered 1 through 20. One card is to randomly drawn from the box.

What is the probability that the card drawn will show a multiple of 4, a multiple of 7, or a multiple of 9?

anonymous · Answer

Alright so you need to list the multiples of each number (4,7,9) until you to the highest multiple without going over 20.

4: 4,8,12,16,20
7: 7,14
9: 9,18

That's a total of 9 numbers. Like the others, you can put that over the total number of cards(20)

So, 9/20
