What is the probability Jason picks an odd number?

yanasidlinskiy · Answer

Umm...I don't know....

jim_thompson5910 · Answer

which numbers in the list below are odd

1,2,3,4,5,6,7,8,9,10

yanasidlinskiy · Answer

1,3,5,7,9

yanasidlinskiy · Answer

So it would be 5

jim_thompson5910 · Answer

so you listed 5 numbers, that's out of 10 total

the probability Jason picks an odd number is 5/10 = 1/2

Wow.....what an easy question I posted........So dumb.....Thanx!!!!

jim_thompson5910 · Answer

1/2 isn't the final answer though (it's going to get us there)

jim_thompson5910 · Answer

you do about the same steps to find the probability of Kyle picking an odd number to also be 1/2

yanasidlinskiy · Answer

So 1/4 right?

jim_thompson5910 · Answer

so the probability of them both picking an odd number is (1/2) * (1/2) = 1/4

this is assuming the two events are independent

jim_thompson5910 · Answer

yes correct
