two dice are rolled, given that the total showing on the two dice is 7, find the probability that one of the dice shows the number 2​

For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.

Step-by-step explanation:

2/36

Step-by-step explanation: there are 36 possibilities when you have two dice. each dice have one two on them. therefore you have a 2 out of 36 chance of rolling a 2.

i belive those are the ones that are under 90 degreese.
