Marti rolls two dice. what is the possibility that the sum of the dice is 7, given that the first die is a 2?

1/6 i think

Step-by-step explanation:

so if the first die is 2 and then a die has 6 sides it would be a 1/6 chance of rolling a 5

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
