Answer:
6
Step-by-step explanation:
probability of answering a question correct p=1/4
let minimum number number of question that would be unusual =n
hence from binomial distribution P(X>=n) <0.05
by solving:
n=6
it would be unusual to get 6 or more questions correct by guessing alone.
First, we add the amount of viewers together. {1,771,548 + 5,861,014 = 7,632,562} Rounded to the nearest thousand, {7,632,562} is B. 7,600,000. Remember, when rounding, 5-9 you go up a number, but any number 1-4 is rounded to 0.

22/8-3/8
This equals 19/8. Because this cannot be simplified any further, the answer is 19/8 k.
