Answer:
This only has answer 1. these proofs are really long, so hard to fit them all in one answer.
Step-by-step explanation:
: Will be used very often so just remember this equality.
1. Multiply 
When we factor out the terms, we are left with:
We then use the rule above and convert it to
:
Probability of getting an even number (2,4,6) out of (1,2,3,4,5,6) =3/6=1/2
The probability of getting x even number :
(using the binomial probability)
30Cx (1/2)^x . (1/2)^(30-x)
Answer:
The answer is D.
