Answer:
(a) 0.139258
(b) 0.0064827
Step-by-step explanation:
Let the probability that each member makes a correct decision be and the probability that each member makes an incorrect decision be .
From the question,
p and q are mutually exclusive. Hence,
(a) For majority rule, it means at least 4 members decisions are taken. Taking "C" to mean "correct" and "I" to mean "incorrect", we could have 4C against 3I, 5C against 2I, 6C against 1I and 7C against 0I.
The probability of the correct decision being made is
(b)
The answer is the first choice, 3(w-4)=5.
3 times = 3
a number minus four = (w-4)
is five = 5
I hope this helps.
You need to solve for one of the variabkes and then plug it in
when I did one of them I got a=5-3b/2 so after that you plug that in for a and solve for the other variable, hope it helps
I got 0.0389875 hope its right
