Question

PLZ HELP You roll a number cube twice. What is the probability of rolling a 2 first and then rolling an odd number?

Answer 1

Answer:

1/12

Step-by-step explanation:

The probability on an equal dice is 1/6

There is only one 2 on a dice; therefore, the probability of rolling a 2 is 1/6.

There three odd numbers on a dice; therefore, the probability of rolling an odd number is 3/6 = 1/2.

Because the events are dependent on each other (you HAVE to roll a 2 first AND you HAVE to roll an odd number after), multiply them.

1/6 * 3/6 = 1/12
