Help with probability please!!
1)The bar graph shows the number of representatives from the north, south, central, east, and west regions of a city. According to the bar graph, what is the experimental probability that a randomly chosen representative if from the west region?
A) 1/6
B)1/12
C)1/5
D)1/3

2) which situation uses the law of large numbers?

A) if you flip a coin 800 times,heads will come up about 400 times.
B) if you roll a six sided number cube 2 times, youll roll a 3 about 2 times
C) if it rained yesterday then it will rain today
D) if you flip a coin 500 times, heads will come up about 500 times

For the first one, the graph shows a total of 12 representatives across all 5 categories, and of those, 2 are from the west this is the fraction 2/12, or the answer A) 1/6, meaning that 1 in 6 of the representatives are going to be from the western region.
For number 2, the answer is A) If you flip a coin 800 times, heads will come up about 400 times. This is because the law of large numbers says that as the number gets larger the ratio will get closer to 1:1. This means that since the coin only has 2 sides, it is about 50/50, meaning that of 800, 400 would be heads and 400 would be tails.
Hope this helps! :D
