Probability first song is country is 3/7
probability second song is reggae is 2/6 which reduces to 1/3
probability of both is : 3/7 * 1/3 = 3/21 which reduces to 1/7 <==
3 gallons are in 12 quarts. 4x3=12. 4 qts make 1 gallon
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)

Answer:
The pic is black and you can not see anything
Step-by-step explanation:
Answer:
n = 0 or 3
Step-by-step explanation:
2n² - 5n + 2
2n² - 4n - n + 2
2n(n - 2) -1(n - 2)
(n - 2)(2n - 1)
Prime number is one which is divisible by itself and 1
n-2 = 1 n = 3
2n-1 = 1 n = 0
