Answer:
3. rolling a sum of 20 with two standard dice
Step-by-step explanation:
If something has a probability of 0 then there is no chance of it happening
A standard die goes up to 6. The max sum you can get by rolling two dice would be 12 as 6 + 6 = 12. So you have no chance of rolling a sum of 20 with two standard dice therefore the probability would be 0.

To earn $345.45 simple interest in 7 years, you have to invest $940.
<u>Step-by-step explanation:</u>
Step 1:
 Given details are Simple Interest Rate (R) = 5.25%, Simple Interest (SI) = $345.45, Time (T) = 7 years
Step 2:
 Use the above details to find principal using the formula for Simple Interest (SI) = PRT/100
⇒ 345.45 = (P × 5.25 × 7)/100
⇒ 34545 = 36.75 P
⇒ P = $940
 
        
             
        
        
        
So the total number of students is 50, and you want to find 32/50. and that is equal to 64%
        
                    
             
        
        
        

I only know this because I remember the common fractions, and 1/3 is .3333 repeating.
