You roll two standard number cubes. what is the probability that the sum is odd, given than one of the number cubes shows a 1? show your work.

The average human heart beats 1.15 \cdot 10^51.15⋅10 5 1, point, 15, dot, 10, start superscript, 5, end superscript times per day. there are 3.65 \cdot 10^23.65⋅10 2 3, point, 65, dot, 10, start superscript, 2, end superscript days in one year.how many times does the heart beat in one year? write your answer in scientific notation, and round to one decimal place.

Hi, can anyone show me how to do this problem? 100 points for this. in advance
