OLga [1]

Answer:

  • <u><em>Option A: 500 pages</em></u>

Explanation:

<u>1. Number of pages of the first 5 novels</u>

  • Average = [Number of pages] / [number of novels]

  • 450 pages / novel = Number of pages / 5 novels

  • Number of pages = 5 novels × 450 pages / novel = 2,250 pages

<u>2. Average length of all 6 novels</u>

  • Average = [Number of pages] / [number of novels]

  • Number of pages of 6 novels = 2,250 pages + 750 pages = 3,000 pages

  • Average = 3,000 pages / 6 novels = 500 pages / novel

According to the general equation for conditional probability, if P(AB)= 3/10 and P(B) =2/5, what is ? P(A l B)?
Alexus [3.1K]

The formula for conditional probablity states that

P(A | B) = \cfrac{P(A \cap B)}{P(B)}

Since we know both numerator and denominator, we only need to plug in the values:

P(A | B) = \cfrac{P(A \cap B)}{P(B)} = \cfrac{\frac{3}{10}}{\frac{2}{5}} = \cfrac{3}{10}\cdot\cfrac{5}{2} = \cfrac{3}{4}
