Answer:
1.  P ( tails) = 1/2
2.P (number greater than 4)   = 1/3
3.  P (2 die sum to 8) = 5/36
Step-by-step explanation:
A coin only has 2 possibilities, head or tails, and they are equally likely
So the probability of getting a tails is 1/2 
P ( tails) = 1/2
A die has the numbers 1,2,3,4,5,6 .  There are 2 numbers greater than 4.  They are 5 and 6.  So there are 2 of the 6 choices that work.
P (number greater than 4)  = 2/6  = 1/3
See the dice chart
There are 36 possibilities when you roll the die. 
There are 5 that sum to 8
P (2 die sum to 8) = 5/36
 
        
             
        
        
        
Answer:
24 m/s²
Step-by-step explanation:
Acceleration is change in velocity over time.
a = Δv / Δt
a = (25 m/s − 1 m/s) / 1 s
a = 24 m/s²
