0 cannot be the answer. It makes no sense because you can get a probability of getting tails when flipping a coin.
The answer would be 1/2. You have '2' choices (heads or tails) and 1 out of those 2 times would you possibly get tails.

Answer:
B
Step-by-step explanation:
Divide the sum obtained in preceding step by total number of frequencies.
Answer:
0.9544
Step-by-step explanation:
P(-2 < Z < 2) means that Z has mean 0 and standard deviation 2.
P(−2 < Z < 2) = F(2) - F(-2)
Using the Z - table,
F(2) = 0.9772
and F(-2) = 0.0228
Thus,
P(−2 < Z < 2) = 0.9772 - 0.0228 = 0.9544
This means that data within two standard deviation is 95%.
X(8-4x)/3
Answer: 8x-4x^2/3
