Let A and B be events with P(A) = 0.61 and P(A ∩ B) = 0.39. For what value of P(B) will A and B be independent?
timofeeve [1]

Answer:

P(B) = 0.64

Explanation:

Given

P(A) = 0.61

P(A\ n\ B) = 0.39

Required

Determine P(B)

If A and B are independent, then:

P(A\ n\ B) = P(A) * P(B)

Substitute values for P(A) and P(A n B)

0.39 = 0.61 * P(B)

Make P(B) the subject

P(B) = \frac{0.39}{0.61}

<em />P(B) = 0.64<em> --- approximated</em>

Suppose a friend of yours wants to buy a crystal candlestick. You remember seeing this item at both annie's attic and betty's br
Veronika [31]

The advice that will be given in the purchase of crystal candlestick is to go to

Betty's Breakables if the price is above $25.00.

In this scenario, we were told that Betty's Breakables offers 40% discount,

while Annie Attic offers $10 discount.

<h3>Calculation</h3>

Let's assume the price is $25.00, the discount at Betty's Breakables will be

= 40/100 × $25.00

= $10.

At Annie Attic, he was offered a $10 discount which is the same. However

there will be more gain on the discount if the price is above $25.

Let's assume the price is $30 , the discount will be $12 at Betty's Breakables

which is more than that at Annie Attic in which the discount remains at $10.

It is therefore cheaper to go to Betty's Breakable if the price of the

candlestick is above $25.

All of the following are good reasons to attend postsecondary institutions except:
Ksivusya [100]

The best answer to the question would be (A) longer average life span.

Though there is a correlation between life span and education levels, where the higher your education, the higher your life span, other factors influence how long you life, most notably, of course your fitness levels, health, and diet. Thus, if you want to live longer, it is better to invest your time and effort into those three things instead of attending a postsecondary institution.
