Question

A single die is rolled. Find the probability of rolling an odd number less than 4. (the answer is 2/3 please explain why?)

Answer 1

1,2,3. Which one of these is odd ?

Answer 2

1 and 3

Answer 3

I think you mistyped your question. Answer should be 2/6 but according to the given answer, it seems this question is supposed to be a conditional probability. That is given rolling a number less than 4, what is the probability of getting an odd number? then, answer is 2/3

Answer 4

that's exactly what i thought. I'm taking an online math class. and they gave me that as the answer 2/3.

Answer 5

instead of 2/6

Answer 6

ok, since it's online, anything can happen

Answer 7

the probability of rolling an odd number less then 4....
there are 6 numbers on a die, but there are only 3 odd....1,3,5

so there are only 3 total chances of rolling an odd....and out of that, there are 2 chances of rolling an odd less then 4.

that makes the probability 2/3

Answer 8

thank you thank thank you! that makes perfect sense now @texaschic101

Answer 9

anytime :)

Answer 10

@texaschic101 what you explained is for conditional probability. The question would be:
given that you rolled an odd number, what is the probability you rolled a number less than 4

that is a different question from, what is the probability you roll an odd number less than 4. (the answer here would be 2/6 or ⅓)
