Solve the question: 3(.5y-6)=12

makvit [3.9K]

Answer:

y = 20.

Step-by-step explanation:

Distribute:

$3(0.5y)-3(6)=12$

$1.5y-18=12$

Add 18 to both sides:

$1.5y-18+18=12+18$

$1.5y=30$

Solve for y:

$\frac{1.5y}{1.5}=\frac{30}{1.5}$

$y=20$

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
