According to the "January theory," if the stock market is up for the month of January, it will be up for the year. If it is down

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

$P(X=22)=\binom{34}{22}(0.5)^{22}(0.5)^{12}\\P(X=22)=\frac{34!}{22!\times 12!}(0.5)^{22}(0.5)^{12}\\P(X=22)=548354040\times 5.8207660913\times 10^{11}\\P(X=22)=0.0319184060208\\P(X=22)\approx0.031918$

Hence, the required probability is 0.031918.

If 1-cos A=1/2 then find the value of sinA.

Aneli [31]

Step-by-step explanation:

$1 - \cos( \alpha ) = \frac{1}{2} \\ = > \cos( \alpha ) = 1 - \frac{1}{2} = \frac{1}{2} \\ = > \alpha = arccos( \frac{1}{2} ) =60 {}^{ \bullet} = \frac{\pi}{3} \\ then \\ \sin( \frac{\pi}{3} ) = \frac{ \sqrt{3} }{2}$
