Question

Jason and Kyle both choose a number from 1-10 at random what is the probability that both numbers are odd

Answer 1

Jason:

`(odd)/(total) \\ = (5)/(10) \\ = (1)/(2)`
Kyle:

`(odd)/(total) \\ = (5)/(10) \\ = (1)/(2)`

Now, multiply the two probabilities together:

`(1)/(2) * (1)/(2) \\ (1*1)/(2*2) \\ (1)/(4)`

The answer is 1/4, or .25

Hope this helps!

Answer 2

1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

There are 5 odd numbers from 1 to 10.

So, the probability of choosing a odd number is going to be


`(5)/(10)`


`(1)/(2)`

So, the probability for one person is 0.5

And the same goes for the other person. So, you multiply 0.5 by itself. So the probability is going to be (0.5*0.5) = 0.25
