Answer:
x2 + 7x + 12 = 0
Step-by-step explanation:
(x + 4) (x + 3)
x + 4 = 0 or x + 3 = 0
x = - 4 or x = - 3
Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The proportion people with Blood type AB-negative in the world is p = 0.006
The sample size is n = 30
Generally the distribution of people with Blood type AB-negative follows a binomial distribution
i.e
and the probability distribution function for binomial distribution is
Here C stands for combination hence we are going to be making use of the combination function in our calculators
Generally the probability that at least 2 of them have blood type AB-negative is mathematically represented as

![P( X \ge 2) = 1 - [P( X = 0 ) + P( X = 1 ) ]](https://tex.z-dn.net/?f=%20P%28%20X%20%5Cge%202%29%20%3D%201%20-%20%5BP%28%20X%20%3D%200%20%20%29%20%2B%20P%28%20X%20%3D%201%20%29%20%5D%20)
=> ![P( X \ge 2) = 1 - [1 * 1 * 0.8348 ] + [30 * 0.006 * 0.83986 ]](https://tex.z-dn.net/?f=%20P%28%20X%20%5Cge%202%29%20%3D%201%20-%20%5B1%20%20%2A%20%201%20%20%2A%20%200.8348%20%20%5D%20%2B%20%5B30%20%20%2A%20%200.006%20%2A%20%200.83986%20%5D%20)
=>
Put the dot on the 5 and than go down 4 i think this is right but i might be wrong sorry if i am
