Question

Jason and Kyle both choose a number from 1 to 10 at random. What is the probability that both numbers are odd?. A.1/3. B.1/2. C.1/4 . D.1/8.

Answer 1

There are 100 possible pairs of numbers.
Half of them start with an even number so only 50 have a first odd number.

Of those remaining 50, half of those have an odd second number.
Leaving 25 of the original 100 to have two odd numbers.

P= 25/100=1/4
