Applying the given probabilities, it is found that there is a 0.42 = 42% probability of watching a movie today.
These following <em>probabilities </em>involve a movie being watched today:
- 0.5 of 0.6(if it rains today).
- 0.3 of 1 - 0.6 = 0.4(if it does not rain today).
Hence, adding them:
0.42 = 42% probability of watching a movie today.

Answer:
B. 24d + 4; $76
Step-by-step explanation:
Part 1: If the online store charges $24 per DVD, this is the same as saying "24 multiplied by the number of DVDs bought".
It's given that "d" represents the number of DVDs
- So the first part of the variable expression is: 24d
If the online store also charges an additional $4 per <em>order,</em> that means that it's only $4 extra for the whole order. NOT per DVD you buy.
Part 2: If someone were to buy 3 DVDs, that would mean that d = 3.
To find the total cost, substitute 3 for d into the expression.
- 24d + 4
- 24(3) + 4
- 72 + 4 = 76
- Result: $76
It would be A, most definitely.
