Answer:
<h2>The answer is 3/6. That is simplified to 1/2.</h2><h2>1/2 of the sweaters are blue.</h2><h2>To find the answer you do the blue sweaters over the total of sweaters including the blue ones.</h2><h2 /><h2>That is 3/6.</h2><h2 /><h2>This is the answer but you should always simplify.</h2><h2>To simplify, you divide. In this case, divide by 3.</h2><h2 /><h2>3 ÷ 3 = 1</h2><h2>-------------</h2><h2>6 ÷ 3 = 2</h2><h2 /><h2>So the answer is 1/2. </h2><h2 /><h2>You might be interested in
Answer:
The required probability is 0.031918.
Step-by-step explanation:
Consider the provided information.
It is given that According to an article in The Wall Street Journal, this theory held for 22 out of the last 34 years.
Therefore n=34
The probability it is either up or down is 0.5.
Thus the value of p =0.5 and q = 0.5
Now calculate the probability
Let X is the number of years that theory held.
X has a binomial distribution with n=34 and p=0.5
Hence, the required probability is 0.031918.
