Question

You roll a number cube twice. Find the probability of the event in fraction form. Need help with #2 and #3

1. Rolling a 4 then an even number.
1/12

2. Rolling a 3 then a 3

3. Rolling a number less than 1 and then a number less than 2

Answer 1

first one is right

Answer 2

second one, same idea. multiply

Answer 3

first one you got by\[\frac{1}{6}\times \frac{1}{2}\] right?

Answer 4

yeah

Answer 5

there is no number <1

Answer 6

oh right

Answer 7

in a cube die numbers are from 1,2,...,6

Answer 8

so i guess you are supposed to say "zero"

Answer 9

so #3 would be 0?

Answer 10

yes, impossible event has probability zero

Answer 11

okay and what about #2? how do i find the fractions i need to multiply

Answer 12

What's the probability of rolling a 3 when you roll a die?

Answer 13

#1 is harder than number 2, if you could do 1 you should be able to do 2.
