To calculate for the standard deviation given the
probability, we use the formula:
s = sqrt (n p q)
where s is standard deviation, n is number of samples = 11,
p is probability of success = 0.7, q = 1 – p = 0.30
s = sqrt (11 * 0.7 * 0.3)
<span>s = 1.52</span>
1/2 times 1/2 times 1/2 is 1/8
Probability of head times the probability of head times the probability of head
So 1/8
She isn't correct. 43 is a 2-digit odd number but it isn't composite. It's a prime number.
