A coin is flipped and a normal dice is rolled. what is the probability of getting a tail and a five?

0.083

Step-by-step explanation:In case of coin ,

Total possible outcome is 2 and sample space is 1

So, probability of getting a tail =  1/2  

Now, in case of dice ,

Total possible outcome is 6 and sample space is 1

So, probability of getting a 5 =  1/6  

Now, since both events are independent therefore,

Required probability is = P[getting a tail] × P[getting a 5]

1/6*1/2=0.083

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
