Answer:
<u>Create a function representing number of published articles per month:</u>

Where:
- a = total number of articles published
- m = number of months
- 12 = slope = number of articles published per month
- 60 = y-intercept = number of published articles at the start (month 0)
<u>Now substitute in the values of m to get the a-value:</u>
- m = 1 → a = 12(1) + 60 = 72
- m = 3 → a = 12(3) + 60 = 36 + 60 = 96
- m = 4 → a = 12(4) + 60 = 48 + 60 = 108
- m = 9 → a = 12(9) + 60 = 108 + 60 = 168
3/5 participate in after school sports...
of these, 1/2 play lacrosse......1/2 of 3/5..." of " means multiply..
1/2 * 3/5 = 3/10....so 3/10 play lacrosse
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.
