Answer:</h2>
348in²
<h2>
Step-by-step explanation:</h2>
6*8 = 48. This is the surface area of the largest rectangle.
6*9 = 54. This is the surface area of the top rectangle.
8*9 = 72. This is the surface area of the smallest rectangle.
The total is 72+54+48, so 174.
Because there are two of each rectangle, you times this number by 2.
174 * 2 = 348in².
Answer:
0.25 is the required probability.
Step-by-step explanation:
We are given the following in the question:
Probability that like book 1 = 0.6
Probability that like book 2 = 0.5
Probability that Maria likes both the books = 0.4
We have to find the conditional probability that she will like book 2 given that she did not like book 1.
Thus, we have to evaluate:
0.25 is the conditional probability that Maria will like book 2 given that she did not like book 1.
19/50 = 38/100 = 0.38 = 38% .
