The numbers 1 through 5 are recorded on individual slips of paper and placed in a hat. What is the probability of drawing the 3, not replacing it, and then drawing the 4?

    ok The odd of picking a 3 would be 1 in 5 and after that, the odds of picking a 4 would be 1 in 4...so the combined odds would be: 1over5∗1over4=?

    probability of drawing the 3 is 1/5

    and the probability of drawing a 4 after that would be 1/4, since the person took out the possibility for drawing a 3, again

    do you remember what I said about multiplying the independent events to get the probability of the compound event? If you did, good job
