Answer:
96
Step-by-step explanation:
From the given information:
At 95% Confidence interval level,Level of significance 
0.05, the value of Z from the standard normal tables = 1.96
Margin of Error = 0.10
Let assume that the estimated proportion = 0.5
therefore; the sample size n can be determined by using the formula: 
n = 96.04
n 
96
I believe the answer is 8.2
Answer:
A
Step-by-step explanation:
The chance the coin will show 'tails' is 1/2, since there are only 2 sides to a coin. The chance that the die will show an even number is also 1/2, since half of the numbers on a die are even, and half are odd. But, since both of these events depend on each other, or in other words, are dependent, we have to multiply both numbers. 1/2 x 1/2 = 1/4, therefore your answer is A.
